My OEM had an atrocious 3+2 VRM design with no way to attach a cooler on, so I applied small pea-sized paste on a small circle at the center of each thermal adhesive tape I placed on its MOSFETs with a 12mm fan blowing directly on them. Considering my CPU no longer throttles down during its periods of turbo-boost, I consider it a success.
My guess is that the better thermal transfer heavily suppressed the sudden dangerous temperature spikes that caused stability issues, spikes high enough to crash the system yet so short in duration HWinfo64 couldn't capture it.
For vrms use gummy thermal paste K5 Pro, Laird Tputty 607 or Upsiren U6 Pro because have much better thermal conductivity than thermopads. Thermal conductive paste is not for that purpose. And for the processor give PTM7950 phase-change thermopad.
you can use it, the problem is not the porpuse, is clean before apply a new one, is difucult and boring clean the old paste in the vrm and the motherboard around
You should try put the cpu fan firing down, the "hot" air will pass through the vrm heatsink and will be for sure under 120 degrees so vrm should be drop down and even the cpu a think cause you have an intake justo over the heatsink, cheers from Argentina 🇦🇷
your best bet would be to get a small pwm fan, about 40mm to 60mm and mount it so that it is blowing directly on the vrm heatsink. you will see a huge difference, mine dropped down to 45-50c. give this a try and you overclock more. cheers!
Blowing directly how though? Like straight down at the motherboard and the vrms (parallel with the mobo)? Or at an angle so it blows on the vrms, but also towards the back of the case aka towards the back fan? Also whats your recomend fan size and distance (fan to vrms)?
@@PFbigfan447 Did you completely remove the thermal pad from under that VRM Heat sink? If then you need to put it back I placed thermal compound on both sides of the thermal pad which absorbs heat better. Without that pad, there is a slight gap as the heat sink isn't making sufficient contact. Give this a try, you should get better. Or you can run a fan there without the heat sink at all. But I would try option 1 first. Good Luck friend
@@MasterJediSean No no, I haven't taken off the heatsinks. I want to add a fan on top of them for extra cooling performance. I was just wondering how did you position and attach the fan on top of them? Is it directly on top of the heatsinks (parallel to the motherboard), is it at an angle so it blows on the vrms, but also towards the back of the case (towards the back fan)? Does it not intervene with air circulation inside the case?
@@PFbigfan447 I basically just used some zap straps and did my best to position the fan to be parallel with the MB. one time I just let the fan sit on the video card and it was loose in the case, there shouldn't be any problems as long as you don't move your tower. Good Luck!
Have u tried using those little tiny noctua fans? Try to put one or two directly at the Heatsink I've seen a video of someone trying it in his HTPC because he had the same problem
Great video man. How did you achieve the liquid cooling on the rx580 a few years ago? just watched your video on the p12 redux, another good, informative video. Peace from New Zealand.
Just saw a bit in the LD01 video (I was actually planning on buying that case but picked up the ps15 instead). How did you cool the vrms specifically? I'm planning on cutting up a 1u server cpu cooler to achieve this. Thanks :)
Hey man, nice video! Maybe you should try adding a new thermal pad with some thermal paste? Perhaps a gap between the heatsink and the VRMs made the results not that interesting
I'm curious as to why you would overclock a home theatre designed system haha? Do you use it for gaming too? Surely an i3 or even Celeron with the cheapest GPU with the necessary outputs would do the job fine?
You have an overclocked SFF HTPC, with VRM’s that are nuclear hot, so your solution to your stability issue… is to further increase the voltage? Yeah, that’s a great way to cause early electromigration driven failure, given your CPU is already approaching TJ-max, not to mention pushing your power delivery even harder, in a system struggling with thermals. First thing I’d do is dump that cooler. A simpler top down cooler that draws cool air in from the top, will help cool the VRMs. Second, you should probably use thermal pads, not grease, for the VRM heatsink. Finally, why OC an HTPC at all?! I’d knock everything down to stock speeds, because the goal is 24/7 reliability (at least with any HTPC I’ve built).
If your vrm temps are high, calculate the height (usually 1mm) and buy arctic 6w/k thermal pad and replace them. The trick is : use gloves and clean the vrm and heatsink with 99.9 percent pure isopropyl alcohol.
@@MrInterpriser to clean no need for gloves. To install a née on high performance thermal pad you need unused gloves. The oil residue in our fingers will degrade thermal pad performance.
On laptop vram and vrms what to use pads or paste and if pads means what size bro pls reply I own rog strix g15 i am planning to repaste on vram and vrms can i use Arctic mx4 paste
I would not do that, thermal pads are the proper use here. Leveling more than one components on the heatsinksurface is hard (some a re higher then others), the thermal pad is thick and with some pressure applied it levels the contact surface. I believe some of your VRMs are better cooled and some are overheating because there is no proper contact with the heatsink. I would just buy and cut a taller heatsink + go back to thermal pads.

Without a full view of your case, it looks like you're starving the airflow to the CPU by having the fan try to pull air away from the motherboard and push it out the top vent. You're likely better off by flipping the fan to pull air from the top vent into the case. Also the 2 fans right up against the video card will do little for case air flow as it looks like the card almost completely blocks them. By flipping the CPU fan to pull air from the vent in you will provide the vrms with some airflow.
I tried making the fan blow down it only made the VRM temps worse as it blow super heated air to the motherboard. The side fans doesn't help much which is why I removed the rear io plate which lets air in and flow over the VRM area. This was the best configuration out of all I tested.
they ''usually'' use ''thermal pads'', then a heat sink!! if U knew there was no chance of electrical contact. U could go with a film of grease, then a heat sink!! good luck!
Ic minus 8 thermal pads are 8watts per whatever they measure thermal conductivity is. Thermal paste is 5-17 watts but is very thin and can sink into the pourous material of the mosfet surface interfacing the heat sink. I think a 1 mm pad would be good for 5 years where the thermal paste can melt off in hours.
You need to undervolt the CPU and you will lose some performance, but the VRMs may be able to sustain that performance instead of clocking the CPU down to 0,54 Ghz
Get a better heatsink ( more find or bigger thermal mass ) slap any fan you have literally any fan will do , you will be surprised, 124 is not ideal for a reliable operation long term.
Your on the right track, but..... Did you use CPU Thermal paste on the VRM's???? Did you measure the thickness of the old Thermal pad before you put the Thermal paste on??? The Thermal pad looked like 2mm, and the amount of thermal paste was defiantly 1mm.... no wonder it didn't have a big enough improvement you didnt use enough..... you want to use 1.3 times the amount of thermal paste as the thermal pad your replacing, not .5 times(for example if your replacing a 2mm thermal pad you want to use 2.6mm of thermal paste at least)...... and you want to use a thick thermal paste and cover the top and the sides.
Can someone answer me. I have used GPU rx580 8gb and its hot realy fast around 82c to 86c. When i open the vrm its not Linked with the heatsink with thermalpad. Is this the cause why the GPU is genting hot? IM waiting my thermalpad from online store ATM. Mine is aorus gigabyte
Pretending to overvolt and overclock an HTPC is just plain stupid. Driving components to the max to gain an insignificant extra performance is just worthless and risky in that environment. I hanve an HTPC based on Ryzen 3400G and i undervolted the hell out of everything of it, it became a ZERO db machine to watch movies and light gaming on it, and if i want high performance and overclocking without making the house smell burnt, i have the desktop PC.
Most YT PC channels just do simple PC builds which is kinda repetitive and boring. This is the kind of content that we need.

the thermal paste will probably be thicc and will dry because there vrm heatsinks always have a gap inbetween vrms for the thermal pads.
I don't think so, the mounting is spring loaded so in theory there is still good contact between vrm and heatsink
You can use copper shims also.
Didnt use enough? I used thermal paste on my laptop VRM's and got a 5c drop in temperature. Made sure I used enough.
A fan pointing to the VRMs directly (if possible) would help ALOT. Look for laptop fans. They run on 5v and use really low wattages.
3d print shroud would help direct the air flow, cheap and customisable
My guess is that the better thermal transfer heavily suppressed the sudden dangerous temperature spikes that caused stability issues, spikes high enough to crash the system yet so short in duration HWinfo64 couldn't capture it.
just a heads up they make bigger heatsinks you can buy just find out the pin distance and then look up Nmm mosfet heatsink
Honda ecus in the 90s at least used what I can only assume is thermal epoxy or thermal paste on power mosfets using the metal case as a heatsink
That's interesting! Thanks for sharing.

Maybe changing the cpu-fan to blow downwards and use the 80mm fans as exhausts - might improve vrm and cpu temps.
Nope its worse. The air from the cpu heatsink is superheated already.
Did you try checking the spacers on the vrm clips? Some you can take off to get closer to the vrms for better contact

Yo does the Noctua fans make much of a difference from the stock fan on a heatsink?
The stock fan is a noctua already
