ok thanks I thought you had the 970 version but good to hear you went for a more powerful one.

there are 1070 cards which fits without mod I could see on this and other threads but I think adding some spacers on the front panel with further sealing could make it with the card you are using

i would prefer to keep my case fully closed to prevent dust from entering

thanks again for the quick feedback

Does anyone else run a push and pull cooler at the front of case exhausting air and 2 x 80mm fans also exhausting air at the rear. I have tried all different combos trying to create positive air flow through the case but for some reason I am getting better cooling with front and back exhausting air??? Idle my i5 6600k o/c 4.4 ghz sits around 25C and under stress testing after gaming to warm the case up temps stay under 55 C. Even my GPU which sits mostly around 2066mhz o/c when gaming is running 5-6 degrees cooler.

Has anyone tried fitting a rather large card like the GTX 1080 Xtreme?

Hey All

Recently completed a build with this chassis.

A quick thermal observation after running a GPU benchmark on a blower style eVGA 1070 all day:

I found that the large 200MM fan has the odd effect of increasing GPU temps! That's right, running the 200MM fan actually increases GPU temps by 5-6C. I've tried switching the perforated panel on the right side (near the SDD/HDD cages) to the top, but this only improved things by about 1-1.5C.

My fluid dynamics theory is that heat "pools" and is trapped just under the top left bracket with nowhere to go. The front 200MM fan actually pushes this heat further into the corner, giving it less chance to dissipate. Shutting the fan off removes this positive differential allowing that circulating hot air just above the GPU heat sink to bleed off into the case. I found the GPU to hover in the 78C range with front 200mm fan on, and 72C with fan off.

Now, the solution is NOT to turn the 200MM off - other components significantly heat up when this is off. CPU and PCH climbed about 8-10C with the 200MM off. It's not a good situation.

Thermaltake has some work to improve this case for blower-style GPUs like mine. I think a good start would be to significantly perforate the sheet metal at the top left corner and into the acrylic window. Reduce the size of the acrylic window if necessary. I may try a mod, but I'm afraid of butchering the case, and the problem won't be solved by just putting a few dozen holes in the top panel. The overall chassis needs better ventilation above the GPU side of the case.

I should note, I have not yet installed two 80MM exhaust fans - I have a pair coming in on Sunday and I will report back if this significantly helps. You may say "duh bro, you need input and output" - and you might be right. But my goal all along has been to reduce fans to keep the whole setup as quiet as possible. Running this GPU under load in the upper 70s isn't terrible, but I would prefer it run cooler and quieter for better OC headroom.

do you have a CPU cooler bit beefier than the standard intel one for example?

for me it helped the push pull air flow and the 2 80mm fans at the back completed the job

i dont have a 1070 far from that but bringing the 200mm fan down to 0rpm didnt help the gpu cooling at all, it was the opposite and i had to add another 80mm fan on The side of the card to bring GPU temps a bit more down(see pic)

again my own experience not set up comparable to yours but.....

I can tell you from my testing that having the front and rear exhausting air from this case gave the best temp results. I too have a blower style gtx 1070. Not only did the gpu temps rise when having one end pulling in air and the other exhausting also the CPU and motherboard were higher. I have an over clocked i5 6600k running at 4.5ghz, the Gtx 1070 over clocked to 2100mhz. With a push pull radiator cooling the CPU and exhausting air through the front and 2 80mm fans on the rear also exhausting air. CPU under stress or intensive gaming never go above 60c, the Gpu sits around 70C under load with a custom fan curve. Any other fan configuration and the temps go up drastically, CPU and motherboard +10- 15C and GPU +7-8C. So for me negative pressure all the way!

Yes, I have a solid aftermarket CPU cooler. This will pull some fresh air that the 200MM brings in the front, and likely helps a small amount with exhausting heat out the back, but this fluid pathway does not change what's going on over the GPU!

Twin 80MM exhaust fans should help - because at a minimum they will reduce the positive pressure inside the case a bit allowing the heat bubble above the GPU to dissipate.

I wish I had room to put an 80MM like where your's is located - this would obviously create a nice fluid pathway

I take it you are confirming my theory this case REQUIRES the use of two 80MM exhaust fans to improve overall thermals?

Your sentence:

"Not only did the gpu temps rise when having one end pulling in air and the other exhausting"

...means when you didn't have two 80MM exhaust fans? If my stock i5-6500 runs in the upper 50s under load, I imagine it'll run even cooler once the exhaust fans are in place. I just hope I can maintain my very quiet PC profile overall.

If the twin exhaust fans improve thermals and keep the GPU closer to 70-72 under full load (I had been running a benchmark all day) - that'll be great. If not, I may consider some modding to direct air over the top of the GPU.

Can the 200mm by turned around to exhaust the hot air instead?

i see

i put the extra fan on the side of my GPU card because of the crappy fan factory fitted on and the fact I was willing to heavily Oc it (its a 750ti by the way)

but your experience and testing is quite important to me because I am planning to upgrade my GPU next year and the 1070 was on the list

honestly I dont think this case is badly engineering from q cooling point of view considering the other ITX designs on the market.

Out of interest, are you driving the fans via a 3rd party software solution like SPEEDFAN or from your mobo and GPU built in software? not sure it would effect your results but I found SPEEDFAN so much better vs my GIGABYTE mobo and GPU offering....
