Sidenote: all benchmarks were performed with CPUs undervolted to -70mV on CPU and GPU. WIth i7-4980hq I additionally increased power limit to 55W long term and 75W short term
What power limit you would recommend for an i7-4800MQ? Currently I have the stock limits, turbo boost power max 37W and turbo boost short power max 47W.
I would be careful with the power limit. Even if you will able to solve the thermal issue probably you would need to do something with the motherboard to prevent its power limit. Especially on laptops, the factory is more likely under design the PCB rather than over. So if the MOSFETs did not blow up :) may you will need to add some extra capacitors onto the VCORE and the GPU power rails, and bigger power brick would not hurt either.
A liquid metal tip: you should NEVER apply liquid metal directly to the die! It might squirt out of the syringe, and to all over other components. You should apply it to a cotton bud/swab, and then to the component. Many people killed their computers doing it incorrectly. This method was endorsed by Buildzoid (overclocker) among other people.
I will say, it isn't hard to apply if you're careful. If you SLOWLY squeeze the syringe and be ready to pull back the second it comes out, then you're good. I've never had issues applying directly to the die, and I equate that to not being ham fisted with it.
Also, you can probably get the paste off with isopropanol and a toothbrush. If that doesn't work, you could also get it fixed by professionals like Louis Rossmann, who has a channel where he posts videos of the repairs.
Perhaps the CPU height (with the adapter) affects the mounting pressure of the cooler, or somehow prevents it from mounting properly. And in that sense, the mx4 could have filled up the gap better than the liquid metal, surpassing the performance of liquid metal. Just what I thought in mind.
Well maybe its because to the height difference that it is causing problems . this CPU is soldered to a pcb making it much thicker then a normal CPU , this heatsink also needs to make contact to the chipset... maby a pad on the chipset would make it thicker and even things out. letting the heatsink make beter contact to the die but i do not expect it to be a lot better in temperatures then good thermal paste because you are already making contact with the bare die.
Hi Wolfie. For you thermal problem- use "ThrottleStop" with PL1 and PL2 changing them form 37/47 to the 47/58. Also, undervolt of -90mV for the CPU, GPU and cache.
I love your channel dude! I follow it since you were dabbling around with x220/x230 and you also inspired to get me one, which served me as a great work machine for a good year Keep up the great work ^^
I'm also planning on buying one once I have some other things sold. The three two things I plan to do to ensure stability are add extra pipes to the heatsink and bios hack the T440p and undervolt the cpu. Hopefully this will be enough to reduce any throttling.
Thanks for this! Maybe when one day someone develops a custom made heat-piping for the T440p with a better cooler things like these can work it our better.
You beauty of this CPU is that you can get DRM support on macOS as it has the same ID(s) of the original macbook pro iGPU(s). Extra bonus, you can install the fan with heatsink from a model with Nvidia GPU, it will cool your Intel only T440P much better thanks to the extra pipe not being used since no GPU.
Wolfgang's Channel Do you like the t440p keyboard? I had to remove that plastic frame because it was no way in hell I could mount it. The HP Haswell Probook has a better keyboard in my opinion.
So basically applying too much liquid metal will afect negatively the thermal performance. That's a very great tip of how to use this compound the right way (and very difficult too).
I had a 2015 Macbook Pro for a while with this CPU and it is a BEAST! In my experience it's the most powerful mobile CPU intel made until 8th gen. Also, I had no dedicated graphics card yet the Iris Pro was able to edit 1080p video with no issues and do some light gaming.
I just bought a 2014 macbook with this processor and I’m super happy with the performance (got an incredible deal), and youtube suggested me this, man the thinkpad community is amazing, modified heatpipes, wow!
@@WolfgangsChannel There is still no detailed comparison video on TH-cam of single- and dual-channel RAM, frequency and timinigs impact on performance.
Interesting. I've decided to get a 4800mq for mine. I think I've finally concluded that the reason it won't boot is actually the CPU, however I managed to kill that.
Yeah the difference for liquid metal is negligible, and if it's not the bottleneck the risk isn't worth it. Because it's liquid, and corusive I would use the best thermal paste, and maybe look into a better fan. Or looking at similar laptops to see if there's a heatsink with more copper, even it needs to be modified.
@@WolfgangsChannel It's around $90 USD? last I checked vs around $130. The amount of improvement you would have to do to the stock cooling would be immense to overcome its relatively short size, keep in mind Workstations of the era can barely hold 3.7-3.9ghz all core and thats without the L4 Cache and Iris Pro
FYI, that paper sticker thingy on the side of the CPU is a warranty sticker from the Chinese seller, which of course is useless since you got it outside of the US, unless you plan on actually sending it back upon encountering quality issues.
the liquid metal compound requires 2 applications about a week or so appart, if the laptop has daily use. The higher temps of the first week will chemically fuse the compound to the surfaces it is applied, and a gap will be created, between the cpu and the thermal plate. But both surfaces are now in prime condition for the heat transfer that will happen when the second application is done and this gap is filled with more liquid metal.
Imagine cpu i7 4980HQ apply in T540p with big body & more greater cooling than T440p. And also, don't forget T540p also have expresscard slot, so if CPU i7 4980HQ + eGPU expresscard, how much raw power it ?
Nice that you did a video on this. :) My T440p is still rocking the i7 4780hq very nicely. Edit: Link for the heatpipe mod: www.reddit.com/r/thinkpad/comments/cwi4vz/a_dual_heatpipe_heatsink_for_the_igp_t440p/

Thermal compound does not (really) improve cooling. Its purpose is to facilitate heat transfer between the load and the heat-sink. Basically, a "better" thermal compound decreases the latency between the heat coming from the load and that heat transferring into the heat-sink. It really makes no difference if that heat transfer is a second or so behind some other brand. The SAME amount of heat still has to be dissipated by the cooling solution regardless of the efficiency of the compound. Buying these real expensive thermal compounds is a total waste of money, they don't really have any practical benefit at all other than reducing the heat spike when a heavy load is applied. But even cheap 50c thermal compound can handle the kinds of spikes generated by a CPU. Basically, a CPU under constant heavy load will settle on a temperature, there is an initial spike of temperature when the load is applied which then quickly settles down to a steady temperature. All you compound is going to do is (very slightly) change that initial spike and (very slightly) change the time it takes to to settle on that loaded temperature. But either way, no matter what compound you use, that loaded temperature will be THE SAME no matter which brand you use.
True! Honestly, it just seems like the magical 20°C improvements that people report after applying LM come from stock thermal paste going bad (drying out, being applied excessively, etc). It can really help to squeeze the last bits of performance out of desktop systems with good cooling, but on laptops the lowest common denominator is the heatsink P.S. the fact remains that in my case the temperature increase was due to me not applying LM correctly
@@WolfgangsChannel The caveat is of course, that the compound needs to be not compromised and applied correctly. There is such a thing as thermodynamics and there is NO way around it. No thermal compound can magically erase heat. EDIT: In many cases where thermal paste is replaced, other operations have also been performed such as replacing fans and clearing away dust. It is often those other operations that mostly contribute to the increased performance.
@Jmac1000000 Like I said, all it does is improve the latency, (the time it takes for the heat to transfer into the heat sink) which equates to a slightly lower temperature during the transition. It is ONLY during that transition this occurs, on a dead steady load once everything has stabilised they will both perform identically. On a CPU which is changing load all the time it will appear that it has lowered the temperature a little, but that is really a false reading, both highs and lows will converge leaving the average the same. The heat-sink is still dissipating the EXACT same amount of heat on both. I say again, heat cannot magically vanish.
According to Lenovo website specs for t440p is was available with i7-4900MQ series processors from the factory. How did it handle the heat in this factory configuration?
Thx for the good information. You think a game like tekken 7 would run on low settings on a 440p? In first place its not that important but I want to know what are the max. Limits in gaming on this laptop. Thx in advance ✌️
Hello (again :D) Could you post an updated link for the CPU? I can't seem to find the product with the right socket, and that link is no longer available. Thanks
Check out r/thinkpad, they often post links to Taobao sellers. Unfortunately this CPU is pretty rare and hard to get, so sellers are almost always out of stock
is it really safe to apply transparent nail polish to isolate other parts ??? or what kind of nail polish you need for this? i assume theree must be something inside it that makes it not burn and not drive current...
Hi, sorry for my English, I have a t440p and I would like to upgrade the CPU, but I have read your comments and I would like to change the processor but avoid modifying power parameters, etc. What would be the most "stable" model without having to customize factory parameters. Thanks
No difference between thermal grease and liquid metal because performance of this i7-4980HQ in T440p is primarily limited by TDP power limit and not by temperature. Likely using throttlestop you can raise the long term TDP limit from 37w to 47w. To increase to a larger value, you need to unlock advanced menu in the BIOS.
Eh, still a nice gain over the regular dGPU - 730M. I wonder if it's possible to have an eGPU with the T440p over the m.2 slot? I definetely saw adapters for that, like this one - www.banggood.com/NGFF-Version-V8_0-EXP-GDC-Beast-Laptop-External-Independent-Video-Card-Dock-p-1009978.html?cur_warehouse=CN What do you think?
Hello, can you tell me how do i have to search for this on taobao or aliexpress cause i've been searching for "i7-4980HQ for rPGA socket" and i got results but just for BGA socket(original without any adaptation) and i found another one for LGA1150 is this the one that i have to buy?
*Just curious... Instead of the faster..., and thus, hotter..., i7-4980HQ..., have you considered..., or heard of anyone else, using a slower..., and thus, cooler..., Haswell HQ CPU with Iris Pro 5200 graphics..., such as the i7-4750HQ?*
I have a T440p with a I7-4702MQ, the bench scores you have look like what I used to get before I undervolted it, so even the 4702 will thermal trottle without undervolting. Have you tried undervolting on the 4980HQ it could makk a big difference.
@@WolfgangsChannel Excellent answer... I was also curious... If this 4980HQ is just too hot for the T440p cooling system to dissipate the heat, what would be the feasibility of using a 4750HQ instead? Like the 4980HQ, it uses integrated Intel Iris Pro 5200 (GT3e) graphics, instead of the standard Intel HD 4600 (GT2), but would run at more reasonable clock speeds... For models without the G730M option, it could potentially be a boon..., if there're not technical issues that would preclude its use...

I received the processor today (I live in Brazil) but the thinkpad t440p refuses to boot. any tip? Intel Core i7-4710MQ SR1PQ 2.5GHz Socket G3 Mobile Processor CPU Quad Core - with the i5 it's all good and the seller has stellar ratings on ebay. Maybe a bios update? (I'm using a 135w power supply btw)
First, the fact that you bought it on eBay is crazy -- those are pretty rare and are usually only available in China. Second, I'm afraid there's nothing you can do about it short of checking for any pins that are bent or broken off
im trying to buy a cpu for my self but i have a i7 4700MQ with rPGA 947 socket the website has all LGA 1150 processors .. is this compatible with my socket thanks..
@@WolfgangsChannel Thanks for the advice. Sadly I spoke too soon as my order was canceled. Apparently they are not planning on getting in more stock. It appears you'll be an owner of quite a rare CPU!
Buy a more powerful as in higher wattage , amp power supply and maybe wire the fans to boost to full speed. use a jumper on the input resistor shunt of the laptop input to allow more power in to the laptop . you could open the power supply and alter the voltage slightly to boost the system in put voltage. All things you you could consider and explorer.
I'm in the market for a T440p and will probably be purchasing a 4980HQ to upgrade the CPU. Would you recommend I purchase a laptop with the GT730M or without the GPU? I haven't been able to find any information regarding the 4980HQ installed on a motherboard that also has the GT730M. Would the GPU still work with the Iris graphics?
Yes, it should work. I won't recommend the CPU though, since as you can see in the video, the only substantial improvement from 4702mq is graphics... Which you won't need since you'll be using the discrete GPU anyway.
@@WolfgangsChannel so would I get better performance from discrete graphics or from the CPUs integrated graphics? IE should I just buy a laptop without the discrete graphics if I want to upgrade the CPU in this manner?
They were worse because you applied too much ducktape and the contact was a lot worse because of the lack of the pressure. If you had applied it properly it would have been lowered.
Quick question, should I get the i7-4910MQ? I really want this processor for my t440p I recently just got. Do you think I should get it? Because I really am curious what the thermals are with that CPU. I also have the GT 730m on my t440p.
@@WolfgangsChannel I saw and heard that the i7-8410mq is really good a d the temps are very great under load. I'm considering that one, it's insane the difference between temps with the 4910 and the 8410 haha
There are some other listings on Taobao, but I don't know if they're trustworthy. I bought the CPU from the listing I've linked in the description and I won't recommend or endorse any other ones.
liquid metal performs worse than thermal paste only when the surface of either the die (less likely but possible) or the heatsink (more likely) are not straight. if it's the heatsink that's not straight you can try bending it back into place.
I was thinking the same thing, there is no way that dat cpu is the same height as the official one and probably is thicker and sits at an angle on the heatsink
The CPU is two times thicker than the stock ones. Is there any way to measure how the heatsink is bent exactly and whether there's any way to unbend it
@@WolfgangsChannel in this case i don't think the heatsink is bent. as pc tech tips commented it's more likely the height-difference between the cpus made it so the back part of the cpu (relative to the direction of the heatsink) makes poor contact with the heatsink. Perhaps try bending the heatpipe in two places, as to rise the heatsink slightly higher than it's current location, while still being straight.
You should also replace the heatsink with 2/4 heat pipes with quit powerfully fan or just make a water cooling solution for it but it won't be be a laptop
Depends on what you're looking for. X200 is the most popular choice because of the portability. AFAIK there are also Libreboot desktops but I haven't researched that so can't suggest anything

You think a game like tekken 7 would run on low settings on a 440p?
In first place its not that important but I want to know what are the max. Limits in gaming on this laptop.
Thx in advance ✌️
Hello (again :D) Could you post an updated link for the CPU? I can't seem to find the product with the right socket, and that link is no longer available. Thanks
Check out r/thinkpad, they often post links to Taobao sellers. Unfortunately this CPU is pretty rare and hard to get, so sellers are almost always out of stock
is it really safe to apply transparent nail polish to isolate other parts ??? or what kind of nail polish you need for this? i assume theree must be something inside it that makes it not burn and not drive current...
I don't know (: I used electric tape but some people recommend nail polish
Hi, sorry for my English, I have a t440p and I would like to upgrade the CPU, but I have read your comments and I would like to change the processor but avoid modifying power parameters, etc. What would be the most "stable" model without having to customize factory parameters. Thanks
No difference between thermal grease and liquid metal because performance of this i7-4980HQ in T440p is primarily limited by TDP power limit and not by temperature. Likely using throttlestop you can raise the long term TDP limit from 37w to 47w. To increase to a larger value, you need to unlock advanced menu in the BIOS.
I've tried that already and unfortunately, no, this didn't help much
Absolutely untrue. I saw near 20c thermal drops when swapping to LM at idle, and near 10c at full synthetic load under aida64
wait how do you change the mac model to "Thinkpad T440p" instead of "Macbook ..."?
Did you ever make that dual heat pipe mod?
No :(
So basically just go with i7-4910MQ on this one, right?
"incorrect ac adapter" showed up after installing 4700mq. Would update BIO and undervolting work? Or should buy another AC Adapter?
was there enough mounting pressure as well? if not then adding a copper shim might help.
Too much to my taste. I've repasted it three times so far and every time I'm afraid to crack the die
Eh, still a nice gain over the regular dGPU - 730M. I wonder if it's possible to have an eGPU with the T440p over the m.2 slot? I definetely saw adapters for that, like this one - www.banggood.com/NGFF-Version-V8_0-EXP-GDC-Beast-Laptop-External-Independent-Video-Card-Dock-p-1009978.html?cur_warehouse=CN
What do you think?
Guys, does anyone know a place where you could still get those? I would really like to buy one
the CPU or the Laptop?
cpu@@dream0darkness013
Did you try shiming it? lets say with a small 0.5mm shimm. Also what was the price of the cpu?
What power supply are you using after mod? Stock 65 or 90 or 135? or even more?
Hello, can you tell me how do i have to search for this on taobao or aliexpress cause i've been searching for "i7-4980HQ for rPGA socket" and i got results but just for BGA socket(original without any adaptation) and i found another one for LGA1150 is this the one that i have to buy?
*Just curious... Instead of the faster..., and thus, hotter..., i7-4980HQ..., have you considered..., or heard of anyone else, using a slower..., and thus, cooler..., Haswell HQ CPU with Iris Pro 5200 graphics..., such as the i7-4750HQ?*
I have a T440p with a I7-4702MQ, the bench scores you have look like what I used to get before I undervolted it, so even the 4702 will thermal trottle without undervolting. Have you tried undervolting on the 4980HQ it could makk a big difference.
My 4702mq would only allow -70mV, so that's what I did. Same with 4980hq
@@WolfgangsChannel I can get -81mV for CPU, CPU cache and GPU. My Cinebench R15 score is 569 and my Geekbench score is 11875.
@@WolfgangsChannel Hi! Can does work the cpu 4702mq with original bios? THX
*I was wondering... Why are you are running an I7-4702MQ CPU instead of an I7-4910MQ?*
Smaller TDP
@@WolfgangsChannel Excellent answer... I was also curious... If this 4980HQ is just too hot for the T440p cooling system to dissipate the heat, what would be the feasibility of using a 4750HQ instead? Like the 4980HQ, it uses integrated Intel Iris Pro 5200 (GT3e) graphics, instead of the standard Intel HD 4600 (GT2), but would run at more reasonable clock speeds... For models without the G730M option, it could potentially be a boon..., if there're not technical issues that would preclude its use...
if i wanna 15.6" laptop, the t540p are the same that the t440p? that model (540p) represents some disadvantage compared to 440p?
Not sure. Take a look at W541 too, it has a Thunderbolt port
@@WolfgangsChannel thanks bro, i like it, maybe i bought it.
pd: i enjoy your videos, regards from Vzla
Hey ! i'm just curious, how did you find the processor that matches with your thinkpad ? and how did you know that the power supplie will be enough ?
Reddit 😁 I didn’t know if the power supply would be enough, just stuck it in and hoped for the best
What is the most powerful one to put into a X260 ?
I received the processor today (I live in Brazil) but the thinkpad t440p refuses to boot. any tip?
Intel Core i7-4710MQ SR1PQ 2.5GHz Socket G3 Mobile Processor CPU Quad Core - with the i5 it's all good and the seller has stellar ratings on ebay. Maybe a bios update? (I'm using a 135w power supply btw)
Have you applied appropriate and enough thermal paste? Don’t put too much nor too little.
And you can also try updating the bios
@@Dan01-01 yep...
@@Dan01-01 bios update done but no result. It's very strange, the processor runs REALLY hot. It's like a blow-dryer
First, the fact that you bought it on eBay is crazy -- those are pretty rare and are usually only available in China.
Second, I'm afraid there's nothing you can do about it short of checking for any pins that are bent or broken off
nice video bro..just wanna know how to upgrade the graphics
I'll just stick with my i7-4700MQ. It is still a huge upgrade from the stock i5-4200M.
What is the temp and clock speed? HWmonitor or HWinfo?
im trying to buy a cpu for my self but i have a i7 4700MQ with rPGA 947 socket the website has all LGA 1150 processors .. is this compatible with my socket thanks..
I've just put an order in for this chip. Should I use liquid metal? should I change the heatsink?
No, yes, respectively
@@WolfgangsChannel Thanks for the advice. Sadly I spoke too soon as my order was canceled. Apparently they are not planning on getting in more stock. It appears you'll be an owner of quite a rare CPU!
Buy a more powerful as in higher wattage , amp power supply and maybe wire the fans to boost to full speed. use a jumper on the input resistor shunt of the laptop input to allow more power in to the laptop . you could open the power supply and alter the voltage slightly to boost the system in put voltage. All things you you could consider and explorer.
how to buy cooling for t440p with a new coolant agent inside the radiator? i think my radiator is a bit tired
Shouldn't you get the heatsink from the model with the dedicated gpu? It should cool the non gpu model better.
Watch the video
I'm in the market for a T440p and will probably be purchasing a 4980HQ to upgrade the CPU. Would you recommend I purchase a laptop with the GT730M or without the GPU? I haven't been able to find any information regarding the 4980HQ installed on a motherboard that also has the GT730M. Would the GPU still work with the Iris graphics?
Yes, it should work. I won't recommend the CPU though, since as you can see in the video, the only substantial improvement from 4702mq is graphics... Which you won't need since you'll be using the discrete GPU anyway.
@@WolfgangsChannel so would I get better performance from discrete graphics or from the CPUs integrated graphics? IE should I just buy a laptop without the discrete graphics if I want to upgrade the CPU in this manner?
@@IvanLam6 Don't buy this CPU. You'll be better off getting a dGPU model and upgrading it to 4702mq or 4712mq.
@@WolfgangsChannel Alright, thanks man
They were worse because you applied too much ducktape and the contact was a lot worse because of the lack of the pressure. If you had applied it properly it would have been lowered.
Have you tried the 170W Charger via the LM route?
This man rocking the 2013 Pewdiepie cut
Is there still a source that sells the 4980hq with the PGA hm86 socket? The old sources are oos.
Not that I know
Great. In the taobao link, does it cost 850yen? I want to make sure I select the right one. Its the second from left on the bottom row.
I think so. Don't remember exactly
I have a Sager p157sm-a with a 4810mq
Is this compatible?
I know laptop goes up to 4940mx
Quick question, should I get the i7-4910MQ? I really want this processor for my t440p I recently just got. Do you think I should get it? Because I really am curious what the thermals are with that CPU. I also have the GT 730m on my t440p.
I wouldn’t recommend it. Go for 4702mq or 4712mq instead
@@WolfgangsChannel I saw and heard that the i7-8410mq is really good a d the temps are very great under load. I'm considering that one, it's insane the difference between temps with the 4910 and the 8410 haha
How loud is this laptop with i7-4810mq ?
You can upgrade the heatsink to the one that would have come with the nvidia model, it has has 2 heatpipes
watch the video until the end pls :)
I paid 80 for my t440p, guess I'm not buying that expensive CPU for it
Are theire any laptops that are stock with iris/ iris pro graphics? Or is that only for Apple Macs?
There are some but I can't name the exact models
Any updates on the cooling side? I'm kinda waiting for your update to buy my next CPU.
Well the temps are a bit better with a dGPU heatsink but it's still a hot CPU
@@WolfgangsChannel are u planning a quick follow up?
Hello. Wolfgang.
There is no cpu you linked..
May i get another link? and some detail please...
I really want to make a laptop like you...
There are some other listings on Taobao, but I don't know if they're trustworthy. I bought the CPU from the listing I've linked in the description and I won't recommend or endorse any other ones.
since u got this and it has iris graphics maybe like a t440p gaming benchmarks vs other t440p wih 730m and t440p with 4910 without dGPu?
I don't own the CPU anymore
liquid metal performs worse than thermal paste only when the surface of either the die (less likely but possible) or the heatsink (more likely) are not straight. if it's the heatsink that's not straight you can try bending it back into place.
I was thinking the same thing, there is no way that dat cpu is the same height as the official one and probably is thicker and sits at an angle on the heatsink
@@Brandon-uy1uv yes, that is a likely explenation
The CPU is two times thicker than the stock ones. Is there any way to measure how the heatsink is bent exactly and whether there's any way to unbend it
@@WolfgangsChannel in this case i don't think the heatsink is bent. as pc tech tips commented it's more likely the height-difference between the cpus made it so the back part of the cpu (relative to the direction of the heatsink) makes poor contact with the heatsink. Perhaps try bending the heatpipe in two places, as to rise the heatsink slightly higher than it's current location, while still being straight.
Well... Still much cheaper than those new laptops with intel pentium.
And in my book that's a win hehe
You should also replace the heatsink with 2/4 heat pipes with quit powerfully fan or just make a water cooling solution for it but it won't be be a laptop
you sold the cpu? which one are you using now?
Please water cool this bad boy and see how far can it go without thermal nerfs.
Hi, Wolfgang! Thank you for your work.
Question: Is Thinkpad T440p best choise for libreboot?
Hi. The newest Thinkpads that are supported by libreboot were produced in 2008. So no, T440p is probably not a good choice for libreboot
@@WolfgangsChannel what is best choise for libreboot?
Depends on what you're looking for. X200 is the most popular choice because of the portability. AFAIK there are also Libreboot desktops but I haven't researched that so can't suggest anything
The base one use 35w, that 4980hq use 45w
