Fans & Heat
This is a work log so bear with me as I'm learning as I go along.
The ATI GPUs have daft stock fan logic, they run low RPM and waaaay hot at idle - like 80s deg C
Here is a thread where the original poster found a way to set them up manually, slightly more background noise but less toasty toes - much more efficient. You can either toggle the ATI catalyst control back to automatic prior to gaming or load up a high state RPM profile which keeps a constant high RPM. Unfortunately Auto ramp up from custom RPM doesn't work for me.http://forums.guru3d.com/showthread.php?t=265745&page=4
Here is another good ATI thread on HOP:http://www.hardforum.com/forumdisplay.php?f=87
I've ordered some fans to replace the P182 case fans and add an additional intake "breeze". I find the case fans on high are too much, hoping for a dB reduction
In that vein, I've also been testing a lower voltage on the CPU for the same 3400 overclock. 1.26 was fine, now testing 1.25volts. I am also going to put back on the CPU backplate heatpipe cooler when my fans arrive
I ordered these for intake in confined space behind the front air filters:http://www.ncix.com/products/index.p...facture=Noctua
(supposed to be higher pressure to suck the air in through grills)
and these for case fan exhaust replacementhttp://www.ncix.com/products/index.p...facture=Noctua
This is what I have on the heatsink so going to switcheroo with the other design as that supposed to be better for heatsink mount application.
The crossfire cards and PSU combo ment I couldn't put the lower chamber fan in the mid point of the case like its designed to. I read silentpc.com and saw that its possible to squeeze a 20mm fan in front of the lower hard drive cage, but they were none in stock, and I saw users have moved the cage back a little to accommodate regular 120x25mm fans, so that's what I plan to do.
I'm going to try and get an extra fan in the top front 5 1/4" drive bay area - I only have one simple DVD writer there so have room. Going to have to rig up some form of dust bunny filter. That airflow will come right across the CPU heat pipe and CPU cooler to exhaust fans. Mid front fan will go straight to crossfire GPUs and lower front fan will cool hardrives, PSU and feed air into motherboard area. That's the plan anyway. Hopefully it doesnt sound like a hurricane.
Have some fan headers to play with on the motherboard, there is some Asus fan control software here and going to play with that to see if it works. Had a quick look only.
Any builders got recommendation for other fan software control for desktops?
The funky colour is growing on me and the one I have already on the heat sink is basically silent, which is why I stuck with the brand - I read web reviews to check up on them, kind of pricey but quiet.
