Appropriote CPU temp folding?

I'm kind of a newb about cooling, I just slap on the heatsink and leave it. So I recently just setup my new motherboard that I got from an RMA (Soyo KT400 Dragon Ultra) and I noticed with Folding at home running, the temperature is running around 135-140 Degrees (F). Is this an okay temperature? Is this what it should be running or is it too hot? The processor is an AthlonXP 2100+, running at standard clock speed.

    It's hotter than I'm comfortable with, but if it's not unstable, it should be fine.

    since you just got it back, I assume you reinstalled the HSF...cleaned it, put new paste on, etc. You may want to check and see how it's seated :)

    My temps are normally 44c or even a bit higher, but that's @ 2.3GHz with a mediocre fan. Since you're running stock @ 2100+ I'd agree w/ Geeky1 and shwaip: those temps are a bit high.

    Mine vary between 38 and 60 deg C - depends mainly on the ambient temperature. 60 is extremely high.

    If it's a stock heatsink, it often will be pretty high temps when running FAH. Check if it's seated, check if it's using a TIM, and if so, get rid of it and use some AS3 or another decent thermal paste. Another option is to grab yourself a reasonable replacement HSF, they usually come with some heatsink compound for free. Anything is better than TIMs (a little Thermal Interface Material thing, looks like a sticker kinda material).

    Once you've got those temps down you should be able to clock it up a bit more as well and get more WUs done ;)

    Is your case very cramped? If so, can you fit some case fans? If the case temperatures are high, you might benefit from slapping an air intake at the front (bottom) and an air exhaust fan at the back (usually there is a location for the PSU). It should help get the temps down and keep the hard disc(s) cool(er) too, which will keep it working for longer in my experience. Some HDDs run hot as hell without cooling :D

    I have a rather large case, it's a full tower, and I have one 80mm intake and two 80mm exhaust fans. I'm not using the retail heatsink, it's a CyberCooler model, it's pretty big and has a copper heatsink, I think the problem is I need to redo the thermal paste and seat it better, so I'm gonna try that

    friend of mine gave me some Arctic Silver 3 and I reseated it and its now sitting at about 124F under full load, so I guess that's good for now

    Actually, folding increases my CPU temps about 5% above normal average. what you can do is try Arctic Silver Ceramique as the heat will cure it in farily fast and it is quite effective if a thin coat is applied (will be a tib thicker than silicone grease based heatsink compund as applied , and cure down thinner by 1\4 to 1\3 over about 200-300 hours of run time normally but if you are working the CPU full time and it is not resting probably about 200 hours actual runtime max). What I would say is this-- if you fold full time warm boot every 24 hours for first two weeks, get into the BIOS temps and see if average temps go up each warm boot by logging the temps. If over a week to 8 days they drop and then stay stable at near normal (probably if case is vented they will drop to about 35C on that CPU with foldingwith Ceramique on it) you will have a very good stable processor, and if go up significantly look at fanning the box with a higher CFM rear fan to pull heat away from CPU fan right out back of box.

    Camman,

    The difference you saw by just changing the TIM is pretty normal compared to junk/no TIM at all.

    Lets check what the temps are in the room where the pc is at. If you know that, then we can tell you straight away what you can expect. Use F@H since it gives pretty accurate full load temps and that will also help things a lot. As a good general thumb of rule, 25C MAX over ambient on the cpu at load is good/ok for a retail/junk heatsink/fan but pretty high at default cpu speed and voltage. You dont have to care about the case cooling since you have more than enough to do the job.

    For example, as we speak my 2100 @2 ghz is running at 50c with a retail amd heatsink/fan for a XP1700 and wothout any casefans at all at an ambient of 23c. As long as your ambient isnt any higher than that, i cant see any problems getting your temps around those temps. Let me know if there is anything i can do to help out buddy. Give us a rundown of the volt on the cpu/memory/chipset and what the bios report it as.

    Yeah I reckon that's about right ;)

    The ambient in my 'server' room goes up to insane values as I can't afford aircon (I'm in the UK, would cost too much to install & run). When temps are above 30 degC in the room, the additional heat of the 18 PCs really doesn't help stability much :D

    FAH- just curious, no chance of opening a window or something? Short of those few weeks earlier this year (which I swear happened just to spite me, since I'd just gotten finished talking about how rainy, dark and miserable England always was...) it's generally pretty mild in England, so it shouldn't be too difficult to cool them down by opening a window, right?

    For reasons of security - I can only lock the window open a little bit. But the amount of heat generated by the number of PCs I've got, some duallies, some with RAID5 arrays, don't help much.

    It sticks out about 3kW worth of heat continuously. Most of the time it can escape, I'm planning to move the big rack in the loft and tunnel cool air over it, hot air away from it, but I haven't had the time :(

    I'm in a flat, first floor, so it's not that hard to climb up. There are no further floors but I'm just paranoid. I cannot replace the rigs if they die due to the cost :(

    Still, most of the time as said, they're not a problem :D

    Thanks for the info Mac, this is what I'm running at now. I replaced the "cyber cooler" HSF, cause that thing just kinda sucks, I replaced it with the retail heatsink which seems to be working better than that previous one.

    It's cooled down ALOT in my area since I first was having this problem, but here's the rundown anyway.

    Ambient Room Temp: 19.4C
    Case Temp: 25C
    CPU Temp: 48C

    Voltages:
    CPU 1.74v (AthlonXP 2100+)
    DDR 2.46v (three 256mb sticks, one 2700, two 2100)

    the board is a Soyo Dragon Ultra KT400.


    48c (under full load/F@H) is still a pretty high temperature for a 2100 running at stock speed and voltage, isnt it?

    Is the stock heatsink an all-aluminum skived fin unit with a 60x10mm fan? If so, no- that's about right for a 2100 with that heatsink. Which is why it's only rated up to a 2100+, and why I made my dad change the heatsink on his computer. That particular heatsink is a piece of crap- the only thing I've found that it can handle acceptably well is a 1.3GHz celeron :rolleyes:

    It is a little bit high, but I wouldn't worry too much, it's still well within safe limits. Over 55 I'd get paranoid :D
