I picked up a 920 about 2 weeks ago to cool my 2500k. It's running at stock clocking right now. I have a cosmos S case, which has my kuhler running on intake push pull into the chassis, with 3 basic case fans on top exhaust, a Kaze on the floor intake, a intake fan in the front, and a 200mm intake on the side. I have 2 GT's 1850's on the way to replace the stock fans.
My biggest concerns are my temps, and if they are normal, and how I should improve them.
I've been playing some games that put me at about 50-70% CPU load during gaming, which generally has me running at around 38degrees water temp with 45-49 core temp. I've been using one of the recommended programs + hwmonitor to check the core temps. I'm not sure if this is far too high, considering I am not screwing with the voltage at all. Idle, I've seen as low as 29c water temp with 32-35 idle.
Basically though, I wanted to see what you guys think my fan directions should be? I was thinking of moving the cpu fans to exhaust, and then moving gall other fans to intake, including the top fans, and only using my 920, and Video card as exhaust fans. This should drop the internal ambient of the case, since my room is around 74-77f at any given time, and remove the fact that I may be drawing heat from my Video card into the system by having my 920's on intake.
I'm also thinking that due to the cores running as high as they are, my paste may not have been seated fully, even though I did a bit of a spinning action when I put the cooler on (stock paste) to spread it, but may have not done a full spread, so I may loosen the system up and do a bit more spreading w/o lifting the CPU up.
Long post, but I want to make sure this is right, because I'd really like to gun for a 4.3 overclock with stable temps, and have my ram running at 1600, as intended.
Thanks guys, I really appreciate the feedback and insight.
