XP 2200+ Cooling (Overheating Help)

[jthoske]

I run an Athlon XP 2200+ on an Epox 8k3a Mobo.

I have a Thermalright AX-7 HS w/ a 4200RPM Mechatronics fan
( http://www.coolerguys.com/Merchant2...de=001&Product_Code=F-MT80&Category_Code=F-80 )

All of this is wrapped up in this case: (Blizzard 360 from FrozenCPU.com) It has 2 120mm fans on the side, and 1 120mm fan ontop.
( http://www.frozencpu.com/cgi-bin/frozencpu/cas-01.html )

I have Artic Silver 2 between the heatisnk and fan, CPU fan blowing down.

The CPU autodetects @ 1800mhz (correct for a 2200+) and I am running stock voltage (1.65 ?) FSB of 133MHZ

Idling temperature is right around 140 F and load is 147F+(up to 150 at times?)


ANY SUGGESTIONS???

With the 120mm fans going in the case, you have plenty of airlow. I would remove the AX-7 and clean the processor. I apply AS3 to the core with some Saran Wrap around my finger, just dabbing a very thin, even layer to cover the core. Make sure the AX-7 is cleaned well, and re-install. If that does not do it at the low Vcore that you are running, I don't know what will. BTW, what is your room temp?

Be aware that the 8K3A gives true direct-from-core temperature readings. It's one of only two boards that does, so don't compare it against other people's externally-estimated readings with other boards. AMD specs the 2200+ for an absolute maximum core temperature of 90C, and you are reaching only 66C at 150F under load. I'd have to say that's quite normal.

Actually the EPoX 8K5A2/3+ is supposed to read core temp along with the 8K3A and ASUS A7V333 if I'm not mistaken. Still while in spec, I would think that the 2200+ with the AX-7 and good case ventilation should be running cooler than 66C under load.

My watercooled (I know it is a different beast) 8K5A2+/2000+ MP @1900MHz shows an idle temp of 35.5C (95.9F) in the BIOS. This is at 1.95V with a room temp of 77.2F.

the A7V333 finally allows the end-user to read the int. diode. The fact taht COP read the diode wasn't disputed, but with the newest MBM, the diode is finally accessible by a user.

As far as other int. diode boards, I think every Epox KT333 chipset board reads the diode, as does the Gigabyte KT333 rev.2 board.

Beyond that, the diode boadrs are still thin.

Oops, yep, I goofed. I should have said three boards, the 8K3A's, 8K5A's and revision 2 7VRX's. And hey, Mikewarrior2 just made my day with the tip on MBM and A7V333's! Owning an A7V333-R, I was highly bummed that I couldn't get diode readings. Thanks Mikewarrior2! By "MBM", are you referring to Motherboard Monitor 5?

 

[Mikewarrior2]

yep, MBM = Motherboard MOnitor... Go check hte homepage . It isn't too surprising, since Asus works a lot with MBM for compatibility, etc... Now MBM 5.2.0.0 finally gives end-user accessible diode readings .

SO much for it giving you the diode before, though

[mechBgon]

Thanks again for the encouraging news!

Maybe Motherboard Monitor can make the A7S333's non-existent overclocking features materialize for Asus, too! Touche`, Asus... you advertised it, you should supply it. But that's not on-topic... sorry.

OT, but interesting regarding the 8K5A2/3+ From EPoX Tech :

In relation to temperature on 8K5A2+ - a very straight answer - the temperature is read from the in socket thermisistor but does suppport temperature shutdown feature to protect against overheating.

The reasoning is because different cpu's have different methods of reading temperature available, we cannot have the newly integrated overheating protection function working at differing levels of temperature, as with the EP-8K3A - this created a great level of confusion with end users not understanding the difference between the temperature in the core and the temperature in the base of the socket.

As such a level playing field is given to prevent users with XP's setting a 50 degree celsius limit and having the mainboard shutdown immediatley after power-up.

Well, I had the on-die diode problem explained to me so that I understand now. Seems like EPoX 8K5A2+ still reads the on-die diode but it displays the temp read from the thermistor. Simple as that. The on-die diode is used to prevent the CPU from getting fried, and it has a pre-defined temp on which the board will shut down.

Damn, I thought my watercooled temps were too good to be true. :frown: Oh well, even if I am running 7-10 degrees hotter, it still is not bad for 1.95V/1900MHz.

I have the 8k3ae with xp2200+ and it runs VERY hot. I dont know if it is the actualcore voltage or if it is the thermistor reading though. Does anybody know? It gets up to 70 degrees when i am looping 3dmark 2001. It is fairly cool in the room.

All of the specs are
amd 2200+
512 ddr pc2700
ti4400
16xdvd
48x burner
westerndigitial 80gig hd with 2mb cache 7200rpm

Whats your case temp? Which H/S fan are you using.

 

[xWeston]

It is a generic heatsink/fan that came with the processor. The case temp is 27 idle (60 processor idle) so probably about 32 or so, i forgot to look. I have an intake and an exhaust fan.

 

[Toro 45]

Does it have a thermal pad or did you use thermal grease/paste?
Also is your system stable?

It didnt crash while doing a 3dmark loop at 70 degrees, but my room is fairly cool and i live in san diego so it is not very hot here. Im afraid on a hot day or any warmer than it was that it will crash.

I loaded up MBM and the processor was running prime95 just fine with no errors at 75C, it must be an internal diode. There is no way the socket is that high

 

[xWeston]

I just ran my computer all day with the windows shut (to make the room warmer) and i had 3dmark 2001 looping with prime95 in the background, the core read 80C when i came back, and possibly went to 81 or 82. It never crashed though so i am not too worried about the heat anymore. I emailed epox and they said that the 8k3ae does read the internal thermal diode, and AMD says anything under 90 is a safe temperature.

 

[Toro 45]

Thats good to hear it's stable but I really think you should take a look at your cpu cooling.I've seen some guys with temps in the upper 60's but even with a higher reading board, 70's & 80's are to high.

I asked earlier if you have a thermal pad or grease between you cpu & heatsink? The pads usually run hotter or if you installed it yourself you may not have made good contact with the cpu core

Did you install it yourself?

If your not comfortable with removing the H/S you should at least look at putting a higher speed fan on you H/S.

 

[xWeston]

I build systems for people all of the time (thats how i make my money) and no i didnt insteall the heatsink on this one. It came installed. I was going to check if there was a pad or grease but i didnt have the time yet. I usually remove pads and put artic silver on it instead. However, the internal die isnt just a "higher reading board", it's a totally different way of reading the temp.
