View Full Version : P4 1.9 Max Temp

I have P4 1.9 Ghz on Shuttle AR40 mobo..... CPU temp idles about 42 degrees and when the CPU is working hard it rises to high 50's or early 60's depending on how hot a day it is. What sort of temp is good before the CPU starts throttling back ??
I have not noticed any problems with these temps.
Any help greatly appreciated.
Hi! Welcome to our forums.
Your chip's running too hot! 50C is the danger zone for safe running. 50's to 60 is way too hot. You'll have to invest in some better cooling. In the meantime, drop the speed.

I'm not positive but the 2 P4 chips i have (1.7 and 1.8) seem to max at 60C and maybe their limit.
I wouldn't worry one bit. As long as it's below Intels recommended maximum temperature, you should be fine. The P4 does get pretty hot. When I got my first P4 I hadn't upgraded my case yet, and the midi-tower case I had was really crowded, and the case also had terrible airflow. It got up to 71°C under full load, and never, ever, came under 50°C regardless. I now run another P4 chip at 2.2V (see system specs in signature) and it gets up to around 60°C when working hard (and it does so quite frequently). It's absolutely stable, and it's WELL within Intels recommended working temperatures. I don't quite understand this obsession people (sorry Pinky, no offense intended) have with temperatures, as long as it's stable, and doesn't throttle (P4) then what's the problem? Now I do like to get the temperature down, but that's only so I can clock even higher :D Besides, who's to say the temperature reading is accurate in the first place? Anyway, that's just my $0.02
Intel's maximum is not a target running temperature, especially when overclocking with increased voltages!! That is downright dangerous and this is how you hear about people "frying" their chips. High temperatures do so many things to cpus, I can't stress the 'other' golden rule to overclocking enough... "Heat is the enemy."
It's your equipment, do what you will... :rolleyes:
Defintely get a better cooler if you tend to overclock, supposedly its not being overclocked now is it?
Although Intel will say the max temperatures it will run at near those temps you will bump into instablity and your cpu will run like a turtle and eventually that thing will blow anytime its 10 degrees within that limit. Its always good to be on the safe side and if you want to not pay for a good cooler as insurance and rather risk 200 dollar chip then thats your choice! :)
Guys, I absolute agree that when overclocking, and especially when increasing the Vcore substantially while overclocking, one should get the temperature down as far as possible. No argument here. However I honestly don't think high 50's (°C) is dangerous at all. That's ~15°C/27°F below Intels specified max. temperature. I absolutely agree that especially when the chip is getting more Vcore the "limit" is lower. Now how much it should be is another question. High 60's IMO is definitely too high, and that's indeed why I got a better case and some 80mm fans for it myself :) I think a lot of people not even overclocking their P4 cpu's, using the retail Intel heatsink and the Intel thermaltape are seing temps well over 60°C under full load. Even with adequate aircooling. Personally I think 60°C is a reasonable limit when overclocking, but then again that's just my opinion :)

50 is too hot and if its already hot it may get hotter.
People usually getting in 50 will bump obviously into stablity and then crashes as well and then sometimes to lead to burning their comps even though they thought it was resonable temperatures.

No offense, but you don't have a P4 do you? At ~2 Ghz it dissipates around 75 watts (average value, it can be even higher) of heat. It would take a monster heatsink to cool it with a room temp of like 25-30°C, which isn't unrealistic at all. If 50°C is too hot you'd need at least watercoooled sytem to run even 2d apps. in the summer. I'm not saying you're wrong, I just happen to wholeheartedly disagree.
No I don't have a P4 although who said you can not learn about a chip because you do not have it?
Surely your going over the line no one said 20-30 Celius but at least a resonable 40, to prevent any dangers.
The stock does cooling to around high 40's.
And I've seen people with around 44-45 Full load average with people who do have P4 with 1.8gig+
Well think about it this way heat is your enemy to overclock so if you plan to overclock the P4 anyways why would you complain?
The Indiglo Orb was not so bad and I've seen it down to about 42-43 full load for Intel and that isn't an expensive cooler. Usually people even do fine with their stock cooling from 1.7 gig to near 2gig and their temps are fine.
50 maybe too hot because there is something wrong with heatsink placement stock fans don't go that high and I'm pretty sure Intel would have fixed the problem if there was a problem like that which I haven't seen.

THanks for the replies..... I am only using the standard P4 cooling fan ( spins about 3000 rpm )... have just ordered a Thermaltake Indigo Orb... hope this will make some difference.
overclocking my p4 made almost no diffrents to the temps, it gains 2*C when under full load as compaired to the original speed, i am going to swap the thermal tape for some as2 and eventually replace the whole hsf with some water cooling... if only there was a block for the 478
im getting 47 when idle and up to 62 at full load
the room temp these last few days has been 37 or so (crappy summer)

so, have i misinterpreted the intel fan's arguement?
i thought they were saying "p4 runs cooler", but maybe they meant "p4 needs to run cooler".
hmmmm...that seems high to me, but i base that on the fact that everyone rants and raves about how the p4's are supposed to be cool.

look these guys are trying to help, anything over 40C is to hot.
They are rite and out of thousands of post ive read your one of the first person's to stand up for high temps. I understand where your at but you and anyone running that hot is asking for trouble. Yes you can run that way but anyone pushing near the Intel temp limit is gambling and theres just no reason theres to many cheap and free things you can do to get temps down.
PS s tay away from the orb! do yourself a favor and get a good all copper HSF and you will be much happier

id would also like to point out that all amd chips execpt the XP's have there temp messured from the mobo most of the time with a sensor just below the chip, if the sensor doesnt touch the chip you get a ~10 to 15*C cooler readout on your chip
and isnt the cpu throttling ment to protect the chip from high temps anyway?

Actually my system stays rather cool with stock heatsink and fan. Here is why. The room that this system is in stays around 16C (60F) , my computer idles @ 31C (87F) and under load is 48C (118F).
