When you visually test the airflow with the fog machine, don't put it right up to the case and shot the fog in. To get a true reading of the air flow, shoot the fog in front of the PC case from the side and after a cloud builds up remove the fog machine, you will then see how the case/fan performance draws the ambient air in and exhausts it. ;)
I have this case. To be honest it's an oven - very little airflow due to the amount of metal (those holes are tiny and there are nowhere near enough of them). In the end I fixed it by cutting 2 x 114mm holes in the case - one in the bottom so that a 120mm fan can feed air to the GPU and one in the rear so my 120mm AIO has uninterrupted airflow outwards. I also have 2x140mm fans in the front as intake and 2x120mm fans in the top as exhaust. That solved all the issues I was having with case temps. Ryzen 5800X3D, RTX 3080.
Main selling point for this case to me is the lack of a tempered glass window, but still having an acrylic one. Case would of looked ten times better too without the RGB fans and lighted with a led light bar on top which would of lit up the whole case window.
@@ian9615 I got rid of it because my RTX3070 was reaching 83 degrees inside and sounded like a jet engine, even after I added TWO 140mm high rpm fans in the front, this case is okay for lower power components like GTX1050 TI which is 1/3 TDP of 3070
@@klasztornik847 I was thinking to get this case with a RTX3060Ti, do you think this model will also get too hot like your RTX3070 in this case? Maybe I should get a bigger case then.
I am not quite sure if that will work. I would recommend reaching out to cooler master support to see if they could answer that question! Here is the link: www.coolermaster.com/support/ cnl
found this on amazon for $40. Was considering it until I saw how small it is. And that bottom filter looks like a total pain...hard pass. i do like how you can move the front I/O...nice touch
probably, it'll fit all/most micro atx motherboards including the h510, but if you wanna see for yourself go to pc part picker and check for yourself, shows you whats compatible and whats not
I bought one of these and it's garbage, like so many other Cooler "master" products. I ended up having to cut holes just to get some air in there. The filters are less than 50% and the panels behind are also less than 50%. Terrible product.
I'm sorry to hear about your difficulty in finding fans that fit the Cooler Master MasterBox Q300L case. The Q300L is designed to support various fan configurations, so finding compatible fans shouldn't be a problem. It's important to check the specific fan size and mounting options required by the case. The Q300L supports up to six fans in total, including two 120mm fans in the front, one 120mm fan in the rear, and two 120mm fans on the top. Alternatively, you can use a 240mm radiator in the front for liquid cooling. It's recommended to choose fans that match the case's specified sizes and mounting positions to ensure proper installation and optimal airflow. If you're having trouble finding compatible fans, consider reaching out to Cooler Master's customer support or consulting with a PC hardware specialist who can provide you with suitable recommendations based on your specific needs and preferences. cnl

I like how you're saying "now you're looking at" in a different tone.
um. thanks?
@@DigitalDavid David, I think you have to read between the lines there... Even if it is just one line..
Add two upper 120's/140's the front drawing in, the rear top exhausting the heat
Yesssss

Good review. A lot of attention to details. :)
Thanks! Glad ya liked it!!

I have this case, runs a little hot with stock amd cooler
do u have extra fans?
@@arkzwtf yes, 4 120mm. It works fine but stays @ 95°C during cinebench
Interesting. Thanks for sharing your experience with it!
~B
I'm going with a 1660 super and a 12400 for the build I'm doing in this case.
Nice!
~B
How many fans should I buy and which ones lol you recommend the ones you used ? I bought case I just don’t know if it comes with fans
It'll probably come with at least a couple fans
~B
Thank you for this video! I wonder could 3090 FE fit inside?
Thanks for the comment!
That's a great question, but I honestly don't know for sure. Wish I could be more help!
~B
Please god no, I just sold my Q300L 3090 will physically fit, but it will overheat like crazy
@@klasztornik847 Good to know. I eventually choose 4000D. And it is great!

would a 240mm or 360mm AIO fit?
240mm not 360
Do you think I can fit a 3060 Ti Ventus 3x OC on that case? It's a triple fan with 316mm length
I am not quite sure if that will work. I would recommend reaching out to cooler master support to see if they could answer that question! Here is the link: www.coolermaster.com/support/ cnl
cool tiny pc case! will it be able to support a 280m liquid cooler?
I love it! In regards to the cooler, I'm not positive whether it would work or not
~B
David I was wanting to know if you could provide a parts list please?
Excellent video review!! Congrats on having a sponsor!! Promo code DD20 FTW!
you know it!!!
What you think of putting AIO fans 240 mm upfront, adding new 120mm fan rear and puting their 120 mm fan uptop? Thanks!
I like it! Great config!
Can I put 3 120 fans in the front with this case?
No either 2 120mm, 2 140mm or 1 240mm radiator!
Great video David!
Is this case good for the RX 6650XT?
maximum of 360mm length card, look your card model and be the judge !
@@ledivinrs It'll fit. It's around 218mm
Thanks!!

For my pc, the power supply was the hardest part to mount. The screws are in the worst place
Sorry to hear that!
Can you fit an atx power supply? I see lots of room but don't know if the screws would line up
Haven't tried! Let us know if you do! -MB
yes you can. i have a thermaltake psu and it fit perfect
@@jsproductions2772w
Does this case come with any dust filter?
Sure does!
~B
Can it fit a 240radiator in the front?
Yes! Check the images in the affiliate link in our description!
so only room for one HDD. that sucks. so no raid. that answered the question i was looking for.
They make a larger version of this if I remember correctly that might be what you want!
Can you use integrated display and GPU display together?
What do you mean?
I don't believe so. Once you install a GPU the onboard graphics will be disabled on most motherboards.
@@PC_Phil I thought so. Tks
@@DigitalDavid using onboard display and GPU display at the same time. Question was already answered.
can Deepcool AK400 or AK620 be fit inside this cabinet ?
Honestly not sure on that one!
~B
I fit the ak400 or ag400, i forget, but there's clearance and like a half inch room above it.
found this on amazon for $40. Was considering it until I saw how small it is. And that bottom filter looks like a total pain...hard pass. i do like how you can move the front I/O...nice touch
Thanks for sharing! What case did you end up going with?
will a gigabyte h510m fit?
probably, it'll fit all/most micro atx motherboards including the h510, but if you wanna see for yourself go to pc part picker and check for yourself, shows you whats compatible and whats not
I think so!

just custom order tempered glass for it.

how dafuq did u fit the gpu
Gently lol
