3.2ghz P4 / Lian Li V2000 / Ic7 Max 3 Cooling Prob

I'm running a 3.2Ghz P4 Prescott mounted in an Abit IC7 Max 3 (BIOS 1.5). At room temperature (case 34 deg C) the CPU gets hot, even with the 7000 AlCu cooler fitted on the CPU and with its fan on full speed. To aid the cooling of the CPU I've mounted an Accousticool 120mm (which has been hacked to run at full speed - 2000RPM) over the top of it (which accelerates it by 200RPM) mounted on a Zalman fan bracket. The CPU temperature idles at 57-61 Deg C and under 54% load (BoInc) hits 74-78 Deg C!

 

Now these may not be accurate readings as I'm sure the Abit IC7 Max 3 reads CPU temperatures hot, but you can see why I'm trying to get the temperature down somewhat.

 

This little lot is housed in a Lian-Li V2000 case which cost me

Well, seeing as though the prescotts run hot, the max 3 reads temps too high and the 7000 doesnt cool all that great in comparison to some other expensive ones, I'd say those temps are, sorry to say, about right :(

 

Although it does seem a little too high even for the prescott. Do you have an external temp probe you could put on the underside of the zalman heatsink to see if temps are really that high?

Hmm, yeah I know what you mean about the Max 3 and the Prescott :( I had thought that the 7000 was one of the better air coolers which was not 'too heavy' though from what I had read of various reviews?

 

I've no external probeunfortunately, it looks like I may have to invest in one soon though the way things are going.

 

What air cooler would you recommend for use with the above that is not too noisey?

Unfortunately, good air cooling and quiet do not go well in the same sentence :( The best would probably be the SP-94 or the XP-120, both by thermalright. The best fan would be a 92mm tornado, but it is also very loud. Good quiet fans include some of the panaflow range.

Well I've just got the temps down by 5 Deg C by upgrading the BIOS to 1.6 from 1.5, so that has helped, now idling at 54/55 deg.

 

I know what you mean about temp v noise though already with the fans in there so far.

 

I had looked at the SP-94 and the XP-120, but was put off by the mounting directly on to the mother board, plus the XP-120 I do not think would fit on the IC7 Max 3 due to the OTES cooler?

I have an IC7-G and the 3.2 prescott as well. My temps run just as hot. I can stick my hand on the heatsink at full load and not feel much of any heat. The motherboard around the CPU is cool so I'm leaning in the direction of the MB reporting drastically wrong temps on the 3.2 prescotts. I can hit mid 60C temps with 1.38 vcore at load.

There are 2 ways to get a Prescott to run cool:

 

1) watercooling

2) peltier/phase change, etc.

 

The Prescotts will run hot on air cooling no matter what you do, although those bios temps do seem somehwhat incorrect.

Yeah I've come to that conclusion myself, but I think when funds permit I will go with the SP94 and see how that goes, it has got to be cooler than the Zalman 7000 Alcu. The only thing stopping me going down that route now is noise and taking the blasted mobo out again...
