Hi folks,

I'm in need of some advice, I recently installed a new system in a Corsair 250D case.
I'm quite satisfied with the CPU temp at 55C while gaming, though my Asus Strix 1060 seems to be hitting 70C in this case while not playing a graphics intensive game at all (FFXIV).

I have all front 140mm stock fan as intake with a h100i v2 radiator setup in pull as intake, positive pressure, passive rear exhaust.

What I'm noticing is that my case is getting real hot at the metal top plate of the case where the gpu is. What I'm guessing is that there's not enough airflow over the graphics card due to the sheer length of the Strix and the relative position of it to the front case fan. So the heat just accumulates and sits at the top of the card there.

What would you guys do in my position if you want to get the temps down to 60C? Because from reviews this seems to be the accepted temperature for the Asus Strix 1060 on load.

I love the case, even though it took a while to get everything to fit, but now I'm wondering if I shouldn't get a different case instead, maybe a microATX one just for better airflow management.

Thanks in advance!

You need to swap the H100i to push and exhaust, passive exhaust of a system really does not work well. Once you start getting the heat out of the case it should help out.

I do recommend you ignore the whole positive/negative pressure nonsense. PC case fans simply cannot create enough pressure to cause any meaningful pressure inside the case. You wont prevent/increase dust buildup based on fan layout.

70 degrees does seem a bit hot for an aftermarket card, but you shouldn't be too worried about it. Small form factor cases like that usually recommend blower style graphics cards, like the founders edition GTX 1060 since they blow air out the back of the case and not all inside it. There isn't much you can do to lower the temperature with that case. You should be fine as long as the temperature stays below 80 degrees most of the time. It isn't worth getting a new case since the GTX 1060 is able to run fine at that temperature.

Well I realize that you can't possibly prevent dust buildup in a case completely, it's just a matter of mitigation and the 250D does really offer a good capacity of completely dust filtering all the major entries.

I'll try switching the direction to exhaust, perhaps starting with the front fan rather than the h100i fans, as I feel the h100i fans are really needed as intake to at least get some air on the gpu even if it's just the backplate. If that doesn't work I'll consider going exhaust on those as well, it will make cleaning the radiator a tad annoying.

As for the temperatures, I played for an hour yesterday and logged the temps with Corsair Link and it seems like after that time the temperatures even crawl up to 79 degrees, which is very worrisome.

I'm not against getting a new case, but for a small form factor rig I don't really know which other case would be better to solve my airflow issue on the gpu. I've checked a lot of review before buying the 250D and that one came out on top, the only other option that is more expensive seems to be the NZXT Manta case.

Do you guys think that perforating my top panel on the 250D right above the gpu will do much to help the temp buildup or would I have to mod an exhaust fan there on the exterior to actually make a difference?

I don't fully understand, the h100i is mounted opposite of the gpu facing the gpu's backplate while the gpu fans get their own intake from the left side grill.

How do you mean that the h100i is blowing down onto the gpu exactly? And why would the card intake from below? Are you speaking from a regular case layout perspective? Because the Corsair 250D has a horizontal layout with perforated sidepanels on both sides, right for the rad and h100i fans, left for the gpu.

Hmmm, yeah seems like I should have gone for a blower style gpu like the FE editions for this case. But guess I'll have to see how I can make this work somehow, I'm almost home and will do a bit of switcheroo on the fan directions and see what comes out of it, hope I don't have to case mod a better airflow into this case...

Well it definitely appears to be a fan direction issue, switching to exhaust on the h100i or the front fan seems to drop the temps on the gpu with 4-6 C degrees. Couldn't reproduce the crazy 79 C deg from yesterday but could be due to the ambient temperatures, was like 33 C deg yesterday while today is like 23 C deg.

Best result was 61 C deg when putting the h100i to jet engine max, loud as hell but did the trick, guess I might invest in some better fans than the stock fans from the h100i.

I am using a sapphire rx480 nitro (more than comparable heat dissipation) in the Obsidian 250 and a core i5 (no oc). I only use air ventilation. I disconnected the front intake van and added two silent 12 cm fans on the right side as exhausts. So the gpu is managing the intake on its own. And the fans on the right side only exhausts hot air from the gpu. They don't need to handle the fresh air incoming from the front intake additionally. The tower cooler fan also blows towards the right side. With this setup, I can keep the gpu during heavy load in the low 70ies. I was worried about cpu temps, because it is fed with hot air from the backside of the gpu. But the cpu temps stay below 65° C.
I tested the front fan as additional in- or outtake, but with no improvments for the gpu.

Hey @LawlessT

I also having same issue with Stirx 1060 6gb, me and my friend both bought same gpu from amazon and get it imported to Pakistan, my friend's gpu reaches 63 max, while i get 82 degree celcius. I have now Thermaltake Chaser a31 case, 6 fans are installed, 3 intake and 3 exhaust, still the temps are not near recommended.
