Help, a very hot XP 1800 60 degrees plus.

I am having a huge heating problem with my new system. I upgraded to a Retail XP 1800 with the retail heatsink fan. I have been emailing the AMD customer support people and we have modified my Vcore voltage to as low as it will go. By the way, I find a discrepancy between the BIOS and the ASUS Probe utility. The BIOS shows the Vcore at 1.69, the Probe shows it at 1.76.

I used the regular thermal tape when I did my initial install. I just cleaned it off, the best I could, and applied some Arctic Silver 3. My system is running at 60 degrees Celsius with the side of the case pulled off and a 12" Fan on high speed blowing right inside. I can physically touch the heatsink in the middle for more than 20 seconds and not even begin to feel hot. Is it safe to say I am having a contact problem?
What should I do?

Just a note, it was also this hot and hotter before I applied the Arctic Silver. It was clear up to 71 Degrees running Sacrifice. I never tried to touch it before though.

System
Asus A7V266-E, BIOS 1011
Retail XP1800 with Retail HSF
Crucial 2100 256MB
Macron 400W, Dual Fan, PSU (AMD Approved)
 
it sounds as if you're not getting good contact on your die. Check that you have the heatsink installed properly. (you probably did, but it can't hurt). If its on correctly, try lapping the heatsink, or just getting a better one than the retail HSF.

I'd ignore the asus probe reading on the vcore. Mine shows 1.85, but the bios setting is lower (can't remember what exactly) it seems to be a problem with asus boards.
 
My experience with the stock hsf that AMD ships with their procs tells me to stick it in a drawer in case I need to RMA the chip; they are just barely adequate IMHO. I would invest in a quality hsf with a copper bottom at least, like a Thermalright AX7 or SK6 or SLK600 or 800, Alpha PAL 8045 if it fits your board or a Swiftech MCX462-U or MCX370. These are all premium coolers and aren't dirt cheap, but will definitely cool your proc down well. Do a search here and you can probably come up with more, but with any of these you should be pretty satisfied.
 
i am having issues with an asus a7v266 and amd 1.4 tbird with retail hsf. the bottom line seems to be the probe on the asus mb.

with the 1.4 in the asus the temps were around 60. on bootup, the temps started at 40 after only 50 seconds or so. it took 5 mins or so to get to 60.

put the same cpu and hsf in an epox 8kta3 and get temps of 45 idle and 48 running. on boot up the temps start at 28 or so.

the 1.0 tbird that was running at 42 in the epox is now running at 54 to 56 in the asus.

both cases are ventilated and removing the covers only dropped the temps a couple of degrees.

if you can, try the cpu-hsf in another system and see what you get.

"if you can, try the cpu-hsf in another system and see what you get."

Thanks for the advice, I wish I new somebody who had a system to try it in. I am begining to believe it's the MB overpowering the CPU. I have since bought a copper HSF and some Arctic Silver 3 and still can't get the temp down. I put both side cover back on again and ran the UT2003 demo. I was up to 71 degrees and the top of my case getting hot. Well maybe a new NForce 2 may do the trick in a few months, unless AMD says it's the CPU.
 
i have a 1800+ and use the retail HSF with artic silver 3, the temp in the BIOS and PC Alert 4 (MSI software) reads my temp in the mid 40s C
 
I've given up. I think it's a false temp after reading around on the Asus MB forums. I was running the UT2003 Demo and I am at 71 degrees, or not. The top of my case feels warm, but not much warmer than when my P3 700 was running at 49 degrees.
 
I've got an XP1600 mated with an original Millenium Glaciator which I lapped & put some ASII on according to the manufacturers instructions.
My temps at idle are 39/55. Not any better than my old AYHJA 1.4 chip.
(See "My Rig" for more of my system info...including the $175 I sunk into a Lian Li case & Enermax ps, thinking the aluminum case w/4 fans & dual fan ps would help w/cooling. Boy, was I wrong!)
 
OMG I have same problem with you. Seems like 1800 is lot hotter than 1700 and HOTTER THAN FASTER CHIPS!!

I tested with a 2100 and it was more than 15 degree cooler with same fan. With 1800 I was getting around 70c !! on Medium and 60 on High, and this isn't with Stock fan+heatsink, this is with Volcano 7+

So far I haven't figured out any solution to this.
 
Dude, if your case temp is 60C you have a serious case problem. Your fan is holding you to 10C over case, thats pretty respectable. Are you sure you got your F vs. C correct? I would expect values reported by BIOS to be different than values reported while the processor and other components are actively operating.

I have helly problems with heat from my 1800+ but my case is 33C-35C and my proc is in the mid 70s. If my case were in the 60s, I would be dead!

Blow out that case, you should be ok.

As for the voltage. Lower voltage requires higher current to achieve the same power level. Current is the source of heat(electron friction). Dont always think that a lower voltage means a cooler running processor. I believe the earlier processors ran off of higher voltages but were much cooler. But if you turn the voltage up you will get more heat because the current WILL go up. just keep it at stock. thats the best solution.
 
Warthog,

Is your system unstable or having some sort of a problem or are you just "uncomfortable" with the heat?

I run my systems at 97 C CPU temp with no problem. It is the upper limit of factory specs. As long as there is a fan on the HS, that stops thermal runaway and that is all that is important.

At least you you have silence... silence is golden... I have truly understood that phrase since building my computer and going away from my beloved trusty dell.
 
Warthog, please check to ensure that your heatsink is on in the proper direction. Two reasons why this is very important:

  • The heatsink has a step cut into the base on one end. This step allows the base of the heatsink to clear the solid end of the CPU socket. If it's 180 degrees backwards, it will guarantee you cannot get square heatsink-to-core contact.
  • The clip is not symmetrical. If you have the heatsink 180 degrees backwards, or even just the clip, then the clip's pressure point is not over the core of the CPU.

Another thing to be aware of: the stock patch of phase-change thermal compound is ONE USE ONLY. If you install the heatsink, and then start up the system, you've used up your one use on the PCTC patch. If the heatsink is removed after this, you must use a fresh PCTC patch (reference the AMD builders' guide, page 9 (page 15 of the PDF file)). Arctic Silver 3 is a viable alternative, although not AMD-approved, so I'm glad to hear you have some.

However, the most telling remark so far is this:

Try running your system with the case open and a house fan blowing in the side, as an experiment. If this produces big temperature drops, you've found one culprit that needs to be dealt with (bad case ventilation). The temperature of the CPU will go up almost exactly in proportion to the case temperature, all other factors being equal. Tell us more about your case, if you need help with this.
 
Well first...and 1800+ produces beaucoup de heat and as a few have told, retail HSF=adaquate but does not=good. Spend a few dollars and get an aftermarket cooler. Second, and more heartening to you, is that ASUS mobos read on the high end of readings so I wouldn't be worried about your system unless you are having stability problems.
 
I am beginning to wonder if the nforce chipset has anything to do wtih this high heat from the 1800+. I wonder what it will be if I disable sound and network in the bios. Im going to test this.

to the guy proudly proclaiming his 97C temps...It may run now, but I have a pentium 133 in my basement still good. Your chip will be dead and buried in one year. But why should you care? their useless after a year anyway for the gamer 😀 On the real though, you are degrading the life of your chip. It wont happen all at once, but its kind of like eating a burger and fries everyday...

 
Well, what ambient temp are you running? If you're not having a contact problem, etc, then with the stock HSF your case must be about 47-50C, no?

If the 92 or 97 c temp is listed as the upper limit for the design of the chip and that rating is for 300,000 hours ( I don't know the exact number ) but the chip dies in 1 year then that rating is false and cannot be used as the spec for the product (Liabilty, reliability, lawsuits, you get the idea). I spent many years burning in all sorts of electronics in burn in racks and freezers ( have to get the numbers for both ends of the spectrum) to come up with the calculations that determine the specs for products.

ASUS's dont read high, they read REAL 🙂

The maximum die temperature is listed at 90C. Most people are not yet reading the temperature of the CPU with the onchip thermal diode but the one on the motherboard. Thus it will be several degrees off from the die temp. safe to say 10-15C off I would imagine. Plus it will respond to temp changes very slowly.

so 70C is a reasonable MB sensor temp if you want to be sure you keep your processor under 90C.

agree?
 
That jives with my experience and my observations of others' experiences. For instance, the EPoX 8K3A+ is one of the boards that does read from the die itself, and actually, it's rare for people to exceed 70C readings even on those... usually it's in the 60's, unless they have a badly-ventilated case or some other problem. My understanding of AMD's 90C max die temperature was that it's supposed to be the "point of no return," not a normal operating temperature.

For comparison, my AthlonXP 1600+, overclocked from 1400MHz to 1750MHz and overvoltage by 0.1V, reports 58C using Motherboard Monitor 5.2, which takes a reading from the CPU diode (at long last, and no thanks to ASUS, whose utility doesn't :|). And that's with a basic all-aluminum $6 heatsink/fan unit. I must say, I love this 1600+! 😀

 
So there you guys have it. The chips themselves are running at constants in the 70's c range. We'll know about obviously if a chip goes to it's drop dead range, which would be because of thermal runaway.

Bottom line is that Intel and AMD will let everyone know when an ordinary Heat Sink Fan will no longer cut the mustard. That would be the point when the heat generated by a chip can no longer be pulled away enough in real time by a HSF combo to stop the temp from constantly rising (Thermal Runaway). We are not at that point by a long shot.
 
Well this is kind of OT but with my 1800+ AGOGA and Epox 8k3a (it takes the temprature from inside) the temps are (idle/after 30min of Prime95 and the fan is at low speed): 33C/42C, you could say Im quite satisfied becouse I was having 55-65C before 🙂 kind of drop and Im not even finished yet, a 120x120mm fan is yet to install.

Man your really not reading the posts. Plus you are fixated on 'thermal runaway.' Thermal runaway as you call it, will result in instant death. We are not speaking of instant death. I have no idea why you think as long as the CPU runs, its fine.

Dissipating heat is not a linear function anyway.

And your assertion that AMD and intel will let you know anything about what HSF to use is foolish. I myself do have the AMD specification on heat dissipation. But primarily AMD solves this issue by selling retail HSF. I agree that the retail HSF will always be sufficient at AMDs recommended ambient temperatures. But I disagree that AMD will *notify* anyone when anything changes. You have to go find the info for yourself or just buy a retail CPU.
