GAF, I could use some advice. I think I have temperature problems.
Running Trine at 1680x1050 at medium settings for maybe a minute and a half, GPU-Z and Core Temp showed me at these temps:
GPU (Sapphire HD4870 1GB): 88c
CPU (i7-920): 93c/99c/87c/97c
Idle the GPU is around 78c and the CPU around 60c. Prime95 pretty much puts me at 99c across the board, though the system remains stable. But PixelJunk Eden locked up twice yesterday and during the Trine demo a few months back the computer shut off with no warning...so I'm thinking temps are an issue. Nothing is overclocked.
What are the most efficient steps I can take to lower temps? Silence is unimportant. My wallet would prefer that I replace/upgrade one part at a time, but I can easily afford big sweeping changes if needed.
The next planned upgrade was replacing the 4870 with a 7850. (
I am keenly aware of how poor my current GPU's idle temps are.) Will this make dramatic improvements to the system overall, or should I push that off and try an aftermarket CPU cooler first?
The ambient room temperature ranges from 27-32c. Can't change this as it's summer and I don't have central air.
Case is a P-183 with a CP-850. I hear the P-183s are pretty starved for air but don't know if increasing airflow should be a big priority.
Power supply exhausts out the back, but the 4870
intakes from the back. Rear fan and top fan are exhausts, though the air coming out of the top is pretty cool. There's one intake fan (NZXT DF1202512SELN) in front. I stole it out of a case my fiancé had lying around so I have no idea whether it's okay or worthless crap that needs to be replaced.
Cable management is not flawless but I think only the power supply cables and a few SATA cables are hanging out there. Getting it that far was so nightmarish that I'd rather transplant the entire mess to a P280 before attempting to improve it.
Whew! If you've read all that, you deserve a gold star.
