Quiet PC build

GIGABYTE Radeon HD 4850 1GB GDDR3 PCI Express 2.0 x16 CrossFireX Support Video Card GV-R485MC-1GH

Pros: It doesn't have a fan. The GPU runs hot but this doesn't seem out of the ordinary for a 4850 even with a fan. My build is a quiet-PC with an Antec Solo case and a stock Intel Q9550, the Xigmatek HDT-S1283 CPU cooler, and an Antec NeoPower 650W supply, and an Arctic Cooling AF12025 PWM case fan. Basically 3 x 120mm fans in the case. I'm using the ASUS AI SUITE tool that shipped with my Asus P5Q Pro motherboard to regulate the speed of the fans based on CPU usage.

Cons: It uses two slots.

Overall Review: I don't have a fan blowing directly on the 4850. I tried a 92mm front intake fan that the Solo supports that's in line with the card, but it didn't make any difference. As such my idle temps seem fairly high. Around 58C when I have my PWM fans cranking around 1000rpm, and around 64C when they're down around 600rpm. When running 3dmark06 the 4850 peaked at about 77C with the PWM fans running around 900rpm. In the CPU test the PWM fans cranked up higher and the 4850 temp dropped down under 70C. So it seems capable of running hot and stable. My score was 12165. The board seems to work well without direct cooling, but I'd be concerned using a low-air flow solution that can't adjust to the load. btw, I experimented with under clocking but it caused screen tearing on my second monitor. This is a known issue with changing the memory clock.
