Here's my latest iteration of a quiet PC as of 9-23-03.
I was getting bored with my P4 2.4C rig so I decided to try a 3.0C CPU and a new Asus P4P800-Deluxe MoBo. My prior Intel 875PBZ board was stable but Intel's BIOS releases for that board have been disastrous. The last 7 releases have (among other things) disabled the PAT and caused cold boot/reboot and BSOD issues.
Latest Hardware is:
- Asus P4P800-Deluxe with "PAT" enabled in BIOS.
- P4 3.0C CPU
- Thermalright SLK900U heatsink + 92mm Panaflo L1A "BX" rpm monitoring fan @ 9 volts via Zalman Fanmate **Had to speed up fan from 1500rpm to 1650rpm with faster, hotter CPU**
- 2 x 512MB of Mushkin Level II Dual Pack PC3200 RAM @ 2-3-3-6, 2.65V **Will run stable at 2-2-2-6 with 2.75V**
- ATI Radeon 8500, fanless
- Seagate Barracuda IV, 80GB
- Plextor Premium 52x CDrw **possibly the quietest CDrom/CDrw drive I've ever used**
- Seasonic Super Silencer 400w PSU **Noticeably quieter than the Nexus3000 that it replaced, PSU is no longer the loudest component in my system**
- Antec SLK3700 case with 120mm "OEM" Panaflo @ 5 volts as case exhaust fan, 80mm L1A @ 6-ish volts as HDD cooling fan
Pics will follow later.
Here's my temps with the 3.0C replacing the 2.4C:
Ambient temps in my computer room range from the mid 70°F to mid 90°F range during this time of the year. All temps will reflect this spread.
- Mobo temp ranges from 30°C to 41°C at idle, 31°C to 45°C at load.
- CPU temp ranges from 33°C to 39°C at idle, 47°C to 59°C at Prime95 load.
These are perfectly safe temps and this computer runs super quiet at these settings. Even when the temps are at their hottest, the PSU fan does not increase it's speed.
The swap from the 2.4C to the 3.0C required that I increase the speed of my 92mm L1A(BX) CPU fan from 1500rpm to about 1650rpm and temps are still around 3°C hotter at idle and 6-8°C hotter at load. You can
now hear the CPU fan over anything else in the case but just barely and only when the ambient noise level is very quiet. I suspect when it cools down after summer I'll be able to turn the speed of the CPU fan down a few hundred rpm and be back at my prior noise level.
