I have recently bought an athlon xp 2100+ and an Asus a7v333 motherboard. I am having serious heating problems, only just managing to get the cpu temp down from 79 to 62 degrees by taking the sides of the case off, which isn't really a great solution. the rest of the system specs are as follows;
1 IBM 83.4 gb hard drive
1 IBM 16.8 gb hard drive
1 ricoh 40x20x10x cdrw
1 aopen 6x dvd drive
512mb pc2700 ddr ram (generic)
400w psu
Geforce 4 4200 128mb ram
Asus iPanel Deluxe
As you can probably see, the case is pretty much full, and does have a lot of wiring in it. I have installed an 80mm coolermaster fan on the front and top of the case to try to get the air flowing faster past the cpu. The chipset temperature seems to hover around 31C which seems fine. I am using the standard AMD heatsink and fan with some antec silver heat compound, which i think i installed exactly as the instructions said. Does anybody have any major ideas why the board may be reporting such high temperatures? could it be simply that the thermosensor on the board is measuring wrong, because 62 degrees with the case open even seems too high. Thanks, Nick.

That's really hot, I have AMD 1800+
with a MSI KT3 Ultra ARU 4 HD on the RAID 2 CDROM,CDRW and a DVDR (heavy loaded too) GF4 and an old Duron heatsink with a new ball bearing cooler about 6200RPM =)(added by me from an electronic shop) on it, cause with the nu heatsink (supposed to be for XP 2000+ Coolpower the brand,4800RPM,) i get 75 degrees celsius and with my modified cooler smoothly at 42C. An advice doesn't even matter the brand or how much u pay for it, check that heatsink has a good contact with PSU add thermal grease,and the RPMs u get, at least that happens to me ;)
Take Care.

1)The mobo may be configured for an Intel P4 cpu??
2)Also the power supply should be at least 320w, preferably 400w.
3)are you able to take the system back to the dealer or did you build the unit yourself?

In answer to your questions, i built it myself, it will only take amd cpus not intel, and I carefully fitted the cpu with cooling paste, and the RPM of the fan is about 5000 i think, which should be ok i guess.Any other ideas?

Hey jowin:

Check to see if a P4 will fit a Socket A MOBO.

Nick has a 400 watt PSU.

Geeez, Dude . . . (Nick)

Don't you ever read the friggen posts?
Instead of asking the same questions over and over, try to SCROLL DOWN and look for your answer! Your questions have been answered NUMEROUS times already! Stop being so lazy and *SCROLL* a little.
Look at these posts and stop wasting space with the same messages, will 'ya?

>>> Proper cooling? AMD XP1800+

>>> Overheating or bad processor?

>>> Athlon XP 1800+ heat issues.

Look for those posts by scolling down, and you should have more than enough information to get you squared away.


Hey Intel, AMD rulez!

I agree with leembo about checking other posts...but since I'm here...describe you're cooling setup up. Exactly where are these fans located & which way are they moving the air, in or out of the case?

Try to change the position of your fans. If you have extra fans than there should be some difference in 62 C temp. You may have installed fans in such a fashion that they are not doing their work properly.
Also check you have 400W power supply which is too much. 300 W power supply is more than enough.
1) Check your fans' position. you may need to try different positions to see where they will work fine.

the standard AMD heatsink is a very poor preformer. go buy yourself a volcano 7 and put it on and you should see a big temp drop if you install it right.

As for what Sarah said, a 400 watt power supply is most certainly not too much. In some cases, it's too small

I think i've actually set my fan's the wrong way round, which could be causing a bit of a problem, i've got them so its blowing in through the top, near the chip, and blowing out near the bottom, against the natural convection current, sorry for being so stupid, i'll change the set up and report back once done. If anyone has any other suggestions, the help would be appreciated. Also if anyone knows where volcano 7 heatsinks can be bought in the UK would be appreciated. Thanks for all the help, sorry for not reading all the previous similar messages (i'd read a few, but found no help for my exact problem).

Sorry to add another thing to this list, but someone recommended a volcano 7 heatsink/fan, i've looked to buy one but it says only recommended for up to athlon 1900+, does that mean that i shouldn't use it with a 2100???. THanks, Nick.

See what reversing those fans does before doing anything else. If you can bring your case temp down, the HSF will be able to do it's job & you won't have to "waste" your money on the V 7.

It seems like I just have to keep on repeating myself. *MOST* AMD chips in the range of 1.2 to 1.8 Ghz. in speed run *VERY* close to the same temperatures, give or take a few degrees C. Furthermore, the AMD Website (and nobody else can possibly know this better than AMD) states IN WRITING that even temperatures over 60C are perfectly fine !!!

Knowing this, I say yet again, that just about any FSH with a rating up to 1.5 Ghz. will do you just fine! To prove it to you, simply get your case fans running properly as Jam suggested, and then look at your temps again. I can almost *GUARANTEE* you that your FSH is fine!

And by the way, you were already in acceptable, although fairly warm temperature ranges to begin with. For OVERCLOCKING and massive 3D GAME PLAY - heavy duty cooling *MIGHT* be required. But again, that's what your temperature sensor is for, right?

If your temps look good - then don't worry about it anymore! You've been writing about temps for two or three days noe, and I know for a fact that your questions have definitely been answered more than once - even by me, Nick . . .

Yeah, go with what leembo says and reverse the fans. I made the same mistake that you made, Nick, of putting in the fans the opposite direction (front exhaust, rear intake) and when i switched it around to front intake rear exhaust my temps went down from 70C and up to just around 60C. That was with no load. With a full load my CPU temp would shoot up to around 70C, which is why i bought myself a nice little Cooler Master HHC-001 Heatpipe heatsink/fan. Kinda loud (like a mini hair dryer), but it does the job. Got my temps down to around 45C/46C under full load. Around 30 on cold boot and 40 without load.

I also have an ASUS MOBO, the A7V-KT266A with simular problems. I tried other heatsinks, extra fans, but nothing seems to be helping. After that I installed a BIOS upgrade. After that I was able to reduce the CPU-core from 1.800V to 1.750V. My CPU was always at the temp of 62 degrees without sidecover (otherwise more) and while gaming it would turn out to 68 degrees or even a bit higher. Now it is stable with closed cover at 51 degrees, even when I'm gaming or performing other heavy applications. Besides, there is a jumper on ur systemboard for using the internal temperature measuring of your CPU, this one shows a realistic temperature of ur CPU. Let me know if it helps. (It could be usefull to set ur Vcore to 1,65 just I did. System is running stable now.)
