I dont know the reason, but my new P4 2.53Ghz seems to be overheating at stock speeds with the stock fan. It runs at about 53c when idle and at 62-65 when loaded. I use Arctic Silver3 thermal paste, btw. What can be the problem? :(

Thanks.

Perhaps you put too thick a layer of AS3. Is your room excessively hot or something? That's very strange indeed, could be an incorrect temp reading. Sorry.

My room is about 29-30c without air conditioning, and can be about 26c with the ac turned on. The layer of AS3 I put was quite thin, and I dont think that it could be the problem.
It might be an incorrect temp reading, but how do I make sure of it? My BIOS already is the latest version, BTW.
Will a damaged chip work properly, only at higher temperatures? Also whats the normal temp for a 2.53 at idle and load?
Once again, thanks.

Maybe the heatsink is not sitting on the chip right. I'd remove it and see what the "footprint" looks like on the thermal paste. Something is not right. Try reapplying the AS and reseat the heatsink again. Maybe you put too thin of a layer of AS on. My experience is if you get too much on, a lot of the excess just squishes off to the sides of the CPU. Normal temps should be at 10-15 degrees cooler or more for both idle and load. Your load temps are on the verge of thermal throttling. No way would I try overclocking that until you get the cooling under control. I'd try to get it running a little cooler before using it much.

Hey my 2.53 ran about that temp range too with just stock heat sink fan. I wouldn't worry that much. That temp range is still in the operating perameters. I would cool it down myself, but its not neccessary unless you decide to overclock...then do some cooling work...I added alot of case fans it helped alot. I ordered the dragon orb cooler from thermal take not here yet though...

I also ordered Artic Silver 3 but I'm not a believer that it works that great.

I have OCed it to 2.8....but with lots of case fans.

1 90mm x 90mm in back as exhaust by P4
1 pci slot exhaust fan under Radeon 9700
1 80mm x 80mm side window exhaust
2 80mm x 80mm bottom front intake fans drilled holes in front of case too.
Also my power supply pulls air out from inside to outside at top.

This helped cool my machine down to 47 C idle 56 C load.
This is with stock HSF and Oced 2.53 @ 2.8

Hope you get some ideas from this...

This is a silly question, but shouldn't be overlooked. Did you remove the black thermal pad on the heatsink before you put on the AS3?

I would like to know what mobo are you using???

some like the abit bd7II are known to give high temp readings....I'm suprised that most peeps did not ask this already.

if you are using the bd7II, or max boards, then take off about 10c from your temps.

I too would check the foot print on your HS, and try some extra case fans.

good luck

not saying that you are wrong, but if you took ten off for me, i would be at 8'celcius.:D

I can't say if your temps are correct or not jd....yet with your ice cold room temps, I think 8c is not far off.

btw...I finaly saw your pics on the water forum....nice work.

I'm saving up for a dremel now so hopfully I'll lower my temps when I cut my case.

my room temps are going up as we speak...so I'll need to act soon.

room temps are now 70f with the window opened....outside temp is 51f.
as you can see, I get a lot of heat at this time.

bad air flow in case?

AZN

I still didn't cut the front of my case for my 120mm fan...so at least 25% of my fan is blocked ( no true air flow ). my fan is working with a 80mm fan hole.

I checked the heatsink seatings thrice and if the surface of the contact area was flat once, everything seemed alright. As for AS3, I applied just enough so that the color and words of the proccessor is not visible. And yeap, I scrapped off the black thermal pad before applying AS3 too.
My casing is with 6 fans, 4 for intake and 2+1PSU for outlet. The intake air however passes through the hard disks before reaching the proccessor, so it may be warmer by then. But still, the proccessor shouldnt be this hot...
BTW, the stock CPU fan blows the air inwards, to the heatsink, instead of sucking air out from the heatsink.
My motherboard is a MSI 845PE MAX (MS-6580).
Should I get a high performance CPU fan? I saw one that day that costed $40, but it has a heatsink with very fine copper fins and an evil looking fan. A pain in my wallet though. :(
Thanks for all the replies.

i was thinking about buying a 2.53 P4. Is everyone getting this problem ? Do they overclock well ?

Overclocking a 2.53 isnt really a good idea, unless youre a hardcore overclocker planning to use some serious cooling gadgets. :)

I'd like to set the record straight on at least three things.

1) One guy says those high temps are nothing to worry about and to ignore it. That's BS. Heat is the enemy when you're overclocking. The problem is the stock retail heatsink. They work "ok" at default speed for a 2.53, but are too wimpy for overclocking. The three best coolers are the AX-478, Alpha, and Swiftech like I have.

2) I have a lot of respect for Mica, but I don't like people stating that all BD7 mobos register 10 degrees too hot. I seriously doubt that's true. Maybe a few of them have been know to be off somewhat, but there is not much evidence to indicate all of them are that way. Without calibrating this particular mobo, we just plain don't know how accurate or inaccurate it is.

3) The last myth I'd like to address is that the mistaken idea that 2.53 don't overclock very well. Not true. The 2.53 is indeed a good overclocker. Now there might be a couple other Northies that will give you more bang for your buck, but there are plenty of 3 gig 2.53 floating around.

I truly believe that better cooling is the key here.

Well, no one's sure of my problem? A P4 shouldnt run at that ~65c when loaded, stock heatsink or not, no?
Im all outta ideas.
BTW, my CPU fan only runs at approx. 2500rpm idle, 3300rpm when at load. How do I set it to run higher? Thanks.
