I put a Kraken G10 and a Corsair H75 on a XFX Radeon HD 7870 Core Edition
inside of a Nanoxia Deep Silence 4
last night. Was a tight squeeze but it made it and seems to be working well. Total install time took around 2 hours, though I imagine that has a lot to do with my own careful, plodding approach to desktop upgrades. I included a couple of pictures below.
Overall, sound and thermals look (and sound) good. Highest GPU temperature I clocked last night came during a Civilization V test. It was the first game I noticed temperature (and sound) issues that at a couple of points starting approaching 85 Celsius. Highest I saw last night under Civ V was 60.
Couple of points: First, I do not plan on overclocking. I purchased this because my PC's physical location has mediocre (at best) airflow and I have become incredibly picky about noise levels since I purchased a Cooler Master Hyper 212 EVO last year. So my priorities are not maxing out performance but neutralizing excess noise and controlling temperatures during extended gameplay.Warning: Spoiler! (Click to show)
You will see the 7870 has VRM's primarily on the left and, though I did not include a photo, the XFX heatsink and fan does not include any thermal paste over the VRMs nor any contact points to the heatsink. With that in mind I was perfectly happy to only add heatsinks to the VRAM modules, which you can see above.
Performance has been stellar. After I removed the upper HDD bracket in my case (tried to remove the other one but it doesn't want to go anywhere right now) airflow seems to have helped drop those temps down from ~60 Celsius in Civ V and BF4 to closer to 53/54 Celsius, which seems to be what everyone else is getting. Sound performance is good. I don't have a happy, balanced spot yet for my fan speeds. I have an AsRock Z87M Extreme4
and the fan pins are few and mostly 3-pin. I have one H75 fan and the Kraken G10 fan attached to Chassis Fan 1 (4-pin) and the other attached to Chassis Fan 2. My H75 fan is attached to the only PWR Fan connector on the board. If I find a happier place for fan speeds I'll let you guys know.
Overall, quite happy.
