I have a P4 3.2 prescott on a MSI 865PE NEO2-PFS Platinum Edition with an Aerocool HT-101 heatsink and fan (its a beast running 2 fans intake and exaust)with a side intake on the case and an exaust in the back. A 480 watt power supply. With the stock intel hsf on my temps when playing doom 3 were 160-170 degrees. They say these prescotts run hot but DAMN! THAT HOT? So I bought the baddest hsf in town (which was the Aerocool HT-101)Im using arctis silver 5 and for 1 day it ran like a champ staying under 130(playing doom 3). But today guess what, back to 140 and above. Think the hottest was 156. Anyone have any of these chips and what are your temps? Any suggestions would be MUCH appreciated.

Well, that kind of thing, being common with us Athlon fans, we feel your pain. Except with Pentium 4s, less voltage is required. With the higher voltage requirement of Athlons, when overclocking, it can be even worse.

Until I get a better heatsink, supposed to get the heatsink this week, when overclocking, familiar to AMD users, it's around 131 F degrees at idle and at close to 170 F degrees, when running Prime95, Windows would crash (Windows 98 has gave general protection fault error messages before) usually, Windows would just lock up on me.

BTW, despite some people dubbing the Pentium 4 Prescott, "Preshott", it shall not be any worse than AMD. Just get a better heatsink and Pentium 4s often can overclock without any Vcore increase!!! Athlons almost always require a Vcore increase for stability.

Wording is that the Pentium 4 Prescotts can overclock higher than Pentium 4 Northwoods.

With higher frequencies, which was noticed after I upgraded my processor from an Athlon XP T-bred 2000+ AIUCB to an Athlon XP T-bred 2400+ KIXJB, including other processors, we pay the price of higher temperatures.

Please refer to temps in Celsius. Your CPU is about 70C

Im not overclocking my prescott cause 3.2ghz is enough for me. I was just wanting to get it down to a reasonable temp cause i thought 170 was way too hot. One thing though I looked ALL over intel's site for the threshold temp for the 3.2 prescott and its no where to be found I even scoured the web looking and came up with nothing. Does anyone now what is the norm operating temp and the threshold for these chips are?

Prescot is hot; case ventilation is vital to keep everything cool.

I've just tested the Thermalright XP-90 (removal of Mobo is recommendated), which is not much better than SP94 and within 1C with Pheonix 70.

Corsair's Hydrocool 200ex

Look into that, that hsf combo should keep the temps down. The average temp of the prescott should be around 40C to 45C, Give like a celcius or two.

Its normal for ur Prescott 3.2 run hot. It eats up more power compared to Northwood running at 3.2Ghz. I wouldn't worry about the temperature if you system is 100% stable. Intel CPU will begin to slow down if it reach above certain degrees, so if you did not experience any of that, i wouldn't worry about it

Well unfortunately its a well known fact that the prescott core runs at rather high tempratures, next time go with a northwood core

I also have a 3.2 Prescott. When I first got it, it was running at 70+ degrees C. It would reboot all of the time. Then I got it down to 52 degrees C and it was fine for a few months. Now it is rebooting again. I don't know whether this is a hardware or software issue. I am running WinXP SP2 with 1 gig ram. Is there anyway to find out if I did damage to my chip when I first got it.

I chose the wrong profession!

i have been messing around with my CPU for the following days. just found out that dust accumulates HEAVILY (*in caps) on the aluminum thingies behind the CPU fan... what i did was i took a small paintbrush(semi-hard) to reach the aluminum behind the fans. the MAT OF DUST was interfering with airflow from the fans to the HS (<--that is the aluminum?).
also, when vacuum afterwards when you think you have cleaned it enough.

im a newbie at these things, and i cant seem to remove the hsf from the mobo, so i resulted at using the brush to remove the dust.

it did work. to get an idea of how much you can lower your temp from cleaning: before i had 60-62*C idle and highest i got when loaded was 77*C.. that is awfully hot... after cleaning, idle temp became 55*C.

then i further re-arranged the airflows. the side fan now blows air in and the rear fan now blows air out... i decreased the temp by another 3-4*C...

right now, im running at below 50*C idle aand it barely reaches 60*C when loaded. that is satifying for me because i live in the philippines. very warm climate. room temp here is about 30*C...

i have 2 fans infront of the casing: 1 intake and 1 outtake. im planning. dunno if this is very effective but tomorrow, im going to make both fans intake air. my idea is that the more cooler air from the outside gets in, the better it is. that would be 3 fans taking in air and one fan to take all the air out. dunno if it is very effective, but im experimenting...

with the stock HSF from the processor and a couple of cheap 12V fans that i got from my old PC's, i am fairly satisfied with my system. prescott's are meant to be hot :)

one minor setback with what i have is that it will need frequent cleaning than usual. i had to open the front panels for the 2 fans to take air in. imagine the dust!

if you have any thoughts or whatsoever, pls do email me at wenbertdelrosario(AT)yahoo.com

im a freakin newbie and i dont know even how to remove the stock hsf for cleaning. so any ideas would be greatly appreciated.

i have an Intel D865PERL mobo
Prescott 3.0Ghz. not OC'ed

my target is to have max temp of less than 55. im doing more experiments tomorrow :)

thank you so much for your posts! :)

i have a p4 3.2 2gb of ram two wd 74gb 10'000rpm hard drives with a bfg nvidi geforce 6800gt oc 256mb 8x agp card and a 500wps.that being said my temp is 30c=86f too 40c=104f but when i play games and doom3 it go to 50c=122 too 60c=140!!!i dont no what is a go temp.do you guys no?

hi there, ive just built a pc with a prescott p4 3.0ghx on a gigabyte motherboard, it was working fine to start with, but i checked the bios and it showed the cpu was running at over 80 deg c, which after reading a few forums have realised is "damn hot" it has the standard fan that came with the cpu on it which had some grey putty attached i presumed to help the heat transfer, i thought this could be the problem so removed it and applied some thermal cream instead, now it reaches 96 and shuts off. can someone please help as i am new to this and dont know wether i have done something wrong or if i have some faulty parts, the case also has 2 fans and im using a jantech 400w power supply. i realise that the intel heat sink may not be good enough but 96 deg is crazy!!!!!!!!!! please email or post if you have any suggestions,

thanks, pete
