P4 1.8A How hot is too hot? Various other Q's (TH7-II)

Here is my system...

P4 1.8A
Abit TH7-II Raid
2x256MB Samsung 8 Device PC800 RDRAM (Manufactured Week 10 2002)
Antec 635 case.

(I asked for the 16, but the local place I got it from gave me 8 by mistake, but I think I will keep this since it is so new)


How hot is too hot? For running 24/7, what temperature would you stop at, and feel comfortable?

I have it at 1.9Ghz now with the RDRAM at full speed (400Mhz setting in the BIOS I assume or should it be on Auto to scale with the FSB?)

Current temps using the Windbond app they sent are 33 C for the stytem and 45.50 for the CPU. My VCore is set to default in the BIOS, and windbond sees it as 1.44 - 1.46.


Thanks


 
i personally wouldnt want to go over 49*C.

the highest ive seen so far is 47*C running 2.55ghz 1.85v in a 28*C/82*F room.

dont use the stock intel cooler above 1.7v and always use some AS2.
 
Mine is running 46c right now and I am just surfing the web.... It goes to 55 or so at stock speeds running Prime95's torture test. Room is AC'ed and at 72F.

Damn.

Know of any place (national chain) that would have Arctic Silver on a sunday?

Could the thermal pad suck that bad?
 
I am planning on ordering the AS3 today. Locally, all I could find was Antec Silver Compound. 8.2 on the transfer rating. AS3 has a 9.0.

Only problem is I have to order the 6g container because everywhere is out of stock of the 3g packages.
 
Define "a bit"

A couple degrees higher than what it should be... or 5 degrees? You mentioned the highest you have seen is 47C. I hope that is an Idle temp. I am in no danger of frying it am I?


Do you know the best place to buy AC3 and have it shipped overnight? Outpost is out of the 3g packages, and newegg wants $28 to ship that huge 3g container of AS overnight...

Might have to get the 6g I suppose.
 
The thing about temperatures is most processors will stand up to some abuse. The question is, how long do you really want to use the processor? Running it at higher temps will shorten it's life, as will overclocking it, but if you are anything like the PC industry, you will have something new in about a year and it makes no difference what temp you run it at, as long as your system is stable and you feel comfortable with it at that temperature.
 
As MassiveUnit said, higher temps = shorter CPU life. I think that it's best not to take it above 40*c, any more over a sustained period of time, and you'll find yourself looking for a new CPU.
 
Anyone know at what temperature the built in thermal shutdown protection engages? My o/c'ed 2.4ghz ranges from 40C to 56C and I want to be sure my system isnt slowing down at higher speeds because of the temperature.
 
Do not take it above 40C eh?

It idles at 43-45C, and runs at as high as 57.5C under load... at stock speeds... this is using the stock HSF and thermal tape.

Intel says 67 in the max, and I am close to it using their setup, and stock speed.
 
compared to mine, you are very hot!
im idling right now @ 32*C.

but the th7-II is known for high readings - so youd have to compare it with other th7-II owners.
 
OK, then how do I get a real reading? If this board is off by 5-8 degrees then all would be well (still going to go with the AS, but from reading something on Intel's page, doing so voids the warrentee... I don't know how firm they are on that though).


Are there any other TH7-II owners who can comment on what they are seeing?
 
I am running a 1.8 Northwood on a TH7II at 2.4 Gig (133 MHz FSB). Tdle temps are about 108 F (42C) and under load (SETI) they vary between 115 F (46C) and 121 F (49C). This is according to Hmonitor.

I do agree that these temperatures will take some finite life out of the CPU but I do not believe the rate of degredation matters because it is so slow. I rarely get more than two years out of a CPU before I upgrade it to something else. I have overclocked for years and have never experienced a late in life failure. Even if it fails after a year or two, it is still significantly cheaper to overclock a $188.00 CPU to 2.4 Gig and replace it at circa $100.00 a year or two from now, than to buy a $550.00 2.4 Gig CPU and not overclock it. It will take a long time for core temps in the low to mid 120s F to damage a CPU.
 
now my question--do all those temp readings accurate?
I use sis645 chipset--my temp is arround 46C full load--but the heatsink is not even hot or warm.
 
The CPU temperatures are spot readings directly on the silicon. There is a relatively huge amount of energy absorbing mass and energy dissapating surface area between the minute point on the silicon where the sensing diode resides and the heat sink. Therefore, it is very reasonable that you will not see the heat sink anywhere near as hot as points in the silicon. I suspect that programs such as Hmonitor are probably a few degrees off but they are probably very accurate in terms of an overall feel for how hot things are.
 
I have a 2.0A that I've had on three different boards, Epox 4SDA+, Intel D850MV, and now an Abit TH7 II. On the Epox and Abit boards idle temps are about 45C and on the Intel board they were about 33C (all default speeds). These temps were reported by the bios and MBProbe all using the retail hs/fan, ASIII, and the same case set-up. I think that both the Epox and Abit boards report the temperatures a little high.

PS these temps are in a warm room.
