Intel P4 Safe Running Temperature

[Trancendental]

My Mainboard Alarm went off today, My processor was running at 90C (184F)

I had set the alarm to do this a long time ago and this is the first time it has gone off, The fans all still work. It used to run at about 75C.

My question is what is a safe Temp to run a Intel P4 2.533GHz? Its not clocked as it doesn't need to be

It has served me for a good 4 and years I think but I have not got money in the budget for a new machine at the mo

If your fans still working then I'd say your CPU is on the road out, it must be running dead slow at that temp too, had nay resets or suto shutdowns?

I have not noticed any slowness yet, still seems to be running normal.

No Crashes
No Abnormal behaviour (Apart from the alarm)
No Blue Screens
No Illegal Operations
Auto Shutdowns have been disabled and no Resets or sudden stop and starts.

To remedy my problem I changed the warning Temp Alarm to 100C when I installed everything first there was no default set, I had it set for my own piece of mind by now its broken my piece and made me scared

probably just dust build up, intels run bloody hot anyway, my AMD runs at about 42C.

90C is too hot though, should be about 80C max i'd say

well not to alarm you, but it would seem that i have teh same CPU and it sits no hotter than 41 degrees unless playing games then it sits ~50 Id try a bigger heatsink and some cooling compound

Thanks for that

You know what I really can't remember what Temp it used to run at, it might have been around 65C.

Maybe I'll buy a new CPU Fan and see what happens, at the moment the Tower Cover is off, My computer sits Idle most of the time how could this happen? AND WHY NOW

I'm gonna play some NFSMW and see if it blows up or not.

Thats just great Maybe I wont play anything

I'd try putting a massive FMIC on the front of the PC

Keep the cover on! That helps the airflow throughout the case - just make sure the vents and filters etc are not all gunked up. If the temperatures have got high, i suspect your cooling compound (sits between CPU and heatsink) has dried up. If so, theres no great deal of heat transfer to your heatsink from the cpu - hence overheating. Though a new bigger heatsink with larger fan would help

Mine probably sits a little low as im using a pro Lian Li aluminium case with silly amounts of fans- sounds like a Dyson when its on full tilt

Ok I'll pop the cover back on.

I was only using the original fan that came with the Processor, I might purchase one from PC World Tomorrow... or online.. infact I might even have a spare lying about :idea:

Its the cooling compound thats the key - can get from PC World, maplins, most computer places

Sounds like mine - took my 2 front fans out, no difference in mobo or case temp. Much quieter Was a bit concerned that the HDD wasn't being cooled as much, but I think there is a negligable difference. It has its own HDD cooler now anyway

yea they make little difference, i have vario speed controlled case and HDD fans, just the noisy one is the CPU one so cant get away with turning it down Now i got docking station for the laptop and KVM/networking sorted if i want something quiet for browsing etc i just use laptop (deadly silent)

Arctic Silver is the stuff you need for putting between the CPU and the heatsink. There really is no better stuff. When you get your new CPU if there is a pad of heat sink compound on the bottom clean it off and polish the bottom of the HSF. The smoother the bottom the better the heat transfer. Follow the instructions on the Arctic Silver packaging and you have best heat transfer possible.

I'm not certain that the mobo is reporting the CPU temp correctly. 100 degrees is very hot for a cpu, too hot. I'd expect to see damage to the components around the processor. Popped capacitors etc.

Don't get the stuff from PC World.. It's like going to Fiat for wiper blades.. www.cclonline.com have a much better selection of heatsinks at much lower prices. Even choose Maplin over PC World. If you're feeling flush go for a heatpipe technology. These use evaporative gasses to move heat away from the CPU just like in a fridge. My overclocked AMD 64 3000 sits at 2000Mhz (stock 1800Mhz) and only 36degrees. I love heatpipes :worship:

My question is what is a safe Temp to run a Intel P4 2.533GHz?

Depending upon the precise version, 71-72 deg C.

I used that silver cooling paste, seems to have worked but my heatsink is not properly attached to my processor as the top left clip seems to have snapped think that my be part of my overall problem.

I'll try for an identical heatsink as I don't want to dismantle the motherboard and attach and new fitting.

Running at 53C now and quickley makes its way to 75C

Core temp sensors can be around 20C out . Thermistor sensors tended to be in the 15-20C area by default, however it's not unknown for internal diodes to get to that error either.

Anyway it's damn hard for a P4 to get beyond about 70C as throttle back trip is supposed to be at 68C and it'll knock the chip back to a x1 or even x0.5 multiplier (and at those speeds a CPU can run inside acceptable temp ranges on a bare chip!). So if there's no slow down then you've either got a broken motherboard, though I think the CPU not the mobo controls throttle back, or your CPU is actually nearer 70C which isn't great but okay. The fact you've not had crashes suggests is more likely to be the latter.

I have had crashes since I posted no crashes. No blue screens but a lot of programs were "sorry but they needed to be shut down"

The actual temp my Mobo was recording was 90C right now it hits 75C when I got more then a few IE windows open.

I need new heatsink bracket as the one fitted must have broken due to stress or something.

That silver paste works a treat on ots own though

if that doesn't help start using cereal boxes for ducting cool are directly to the CPU or take a look at some where like scan and go for the Zalman options (down the bottom of the page) they ain't cheap but I've got an early version of the 7000B and it'd out lasted all by my chassis with the acquisition of new brackets. And yeah AS is the dogs of thermal compound.
