XP 2100 Overheating!!!

[Alex Iannuzzi]

Hey all,

Today I got a copper heatsink and am using the retail AMD Fan (5000 rpm).
I placed thermal paste on the CPU and put on the heatsink.

The outside temperature is 30C
The room temperature is like 32 C

I boot up my computer it reads 35 C, I think wow that's pretty good lets see if I can say under 50C while under load.
So I begin to run the Distributing Net Client under the project
RC5-72.
I see the temperature of the CPU start rising, 40C and slowly by slowly it gets to 50C, then it starts going higher to 52C. I say to myself I will turn off the computer and boot up again.

So I do that and in windows while in idle the temp reads 54C - But i am doing nothing at all then it drops ot 52-53 and thats as far down as it goes.

Why is it so hot while under idle? Is it because the fan can't take the heat of fast enough so it builds up?
Right now while typing this message it has now reached 55C !!!!!

If i run the RC5-72 program now I know that my system would probably reach like 60C or more.

I need some answers right now before my computer blows.

Also if i use a thermal pad is that better than thermal paste?

Thanks,

Alex.:mad: :mad: :mad:

What particular copper heatsink did you get? I'd reapply the thermal compound. Something's not right.

[Alex Iannuzzi]

I have got the Jagur Copper Heatsink I don't know the model.

I have put enough thermal paste already.

[anubisnyc]

You have nothing to worry about. The CPU generally builds up heat after use. Its 35C at bootup because it hasn't been used enough yet and its still at room temperature. If your temp hovers at the low 50's after full load thats perfectly fine and well within safety limits. As long as it doesn't get into the high 60's (AMD says 90C is its absolute limit). But 53C is fine.

[Alex Iannuzzi]

Ok, now I have changed the fan to a Delta 7500 rpm which is very loud and now the CPU temps are going down. I have added 2 case fans.

Now the idle temp is like 42-45 and full load is like 49-52. This is much better.

Would a thermal pad be better than thermal paste?

[gibsinep]

Yeah those temps are fine.

:t

[j.m@talk]

Wow "Delta 7500 rpm" ear muffs on eh! :eek:

[causticVapor]

Nothing compared to the 8500RPM version. :eek: :eek:

Is there any way I can reduce the sound?

[athlonxp]

buy a reohstat or do it yourself to reduce the voltage to the fan

Well not really, you could try acoustic wadding on the inside of
your case, but at the end of the day shifting that amount of air around is a noisy buisness :(

I have a Delta on my HS however I have reduced the RPM to around 2800 to keep the noise sensible :p

I'm using the extra depth of the fan rarther than relying in its amazing RPM :t

[AllGamer]

Meanwhile we are in the subject

Which FAN is the Quietest of all and has the DEEPest funnel? But still delivering good cold air?

[Babulmiah]

I use a Zalman Flower pure copper HAF and is so quiet, I can't evn hear it when my PC case is shut. Its by far the best HSF I used (and I used about 20 over the last 2 years). but it is pricey.

see quietPc.com for more info.

[paul0660]

What is your case temp? Is hot air able to get out? Also, too much paste is bad, you only need a very thin film for the cpu to make contact with the hs.

[causticVapor]

That zalman is great for passively cooling coppermines and tualatins, with adequate case exhaust, but not XPs. XPs and Tbirds are just too much for it. You might be able to get away with running a 2000+ Thoroughbred at stock speeds, though. :)


Two candidates... Swiftech MCX series... Thermalright AX and SLK series... two fans... sunon TDx, sunon KDx. Nidec and Delta are also good brands.

My case temp is around 37-41 C, the hot air is able to get out.
Yeah I changed the thermal paste to a thin layer and it's the same.

Oh yer sorry guys, it's not an XP 2100 it's a XP 2000. :(

[causticVapor]

Check for pressure differences... my advice -- invest in a quality heasink that'll last you through a 3.3GHz 3700+ processor, like the MCX462+ or SLK-700/800.

[Giblet Plus!]

I think better case cooling is all that's needed.

I have had many customers complaining that the 2100+ are hot and its true my 1800+ idles at 35-39 , the 2100+ idles @ 42. I have tried intake and exhaust fans and that did nothing. so I am gonna replace the stock fans with thermal take volcano 7+'s

[Billforce]

Try VCool for Win either 98 or XP (different program) . I have an AMD 1700+ running at 1900+ at 31 deg C with a STOCK fan/heatsink. Before Vcool it was high 40's into low 50's. Now as cool as the "other side of the pillow". I run dual boot 98SE and XP Pro, the temp. is the same on both systems.

[Neofate]

Hmmmm.. I would make sure that the bottom of your heatsink is flat. Maybe even lap the heatsink for a good 30-45mins to ensure a flat contact surface. Also, make sure your heatsink is on the chip with enough pressure. I had to mess with my retaining clip a little bit to get the appropriate pressure. Factory it was way to tight, after loosening it, it barely made contact and temps would soar. Then after one more adjustment it was perfect.

I have the 2100, and I idle around 33-34, although I am running an Epox 8RDA mobo, so it might be more like 39'ish.

I saw someone say that 90C was the limit from AMD? Wow, that seems a bit high to me? I suppose thats the absolute limit on the CPU die?

[ProphetXTR]

Hey Alex...personally most the fans posted in here suck. I have asked and asked many of the rpo o/c'ers and time and time again I got pointed to the Vantec Aeroflow. I ordered it and it is quiet and very cool.

I have :

XP2100+Rev. B TBred (1.733 ghz) o/c to XP2600+(2.133ghz) w/ FSB at 333
Epox 8RDA+ motherboard
1 gig OCZ Technologies PC2700
PNY Ti4600

I had the XP2000+ and that cpu always runs hot...around 50-55c. I went for one of the o/c'ers dream boards and ordered the XP2100+ Rev. B from NewEgg. My temps are right around 41 idle and 44 under load. Check Vantec Aeroflow for your fan problems and sell the rest on Ebay.

Vantec Website (http://www.vantecusa.com/afc250.html)
EPOX 8RDA+ (http://www.epox.com/html/motherboard.asp?product=EP-8RDAplus&lang=1)

I would also agree with paul0660. Make sure you have barely any paste on your CPU and make sure you have it on the center only. In the case of more is better...it doesn't apply in this case. You want a small glaze on it...around the thickness of a fingernail. I would clean it off completely and reapply it.

[Aznmask]

Did you apply too much thermal paste on the CPU?? czu last time i spread alot of thermal paste on the cpu. Once i turn on the pc it get from 26c up to 52C in 2min. THen my cousin told me to only apply the middle part.

Again, something that accounts for PRESSURE DIFFERENCES, as I said.

And a new Heatsink wouldn't hurt either. :rolleyes:

[Alex Iannuzzi]

I still can't believe that this thread is still popular.

Anywayz, My CPU is getting 50C at max load and the temp here in brisbane is like 30-33C, so that probably why my cpu is getting hot.

Hey Giblet Plus!
I think that i might end up buying the Thermal Take Aquarius II cause here in Brisbane it's price has decreased to $185 AU which is ok. Cause I don't want to spend $300 AU on water cooling because it is too expensive for me and I don't have that much anyway. :eek:

Also my 7000 rpm fan is starting to annoy me heaps :( :mad:

Oh well, It can't be that bad right? :eek:

Will it get lower than 50C at full load?

Thanks,

Alex

[Aznmask]

My athlon 1700xp (oem) temp right now is under 40C it been taht way since.. i bought this
Cooler Master HAC-V81 (http://www.googlegear.com/jsp/ProductDetail.jsp?ProductCode=370621)

Don't get the Aquarius. Go after a Vantec Aeroflow or SLK-900... they're much cheaper, will be quieter than the Aquarius, and will outperform it.

We're talking about mid-speed fans here, which should not be very noticeable. :t

[pandaz3]

I had a 1.4 Thunderbird that ran 62 C or a little higher at times, with a stock AMD cooler. I bought a Vantec 6040 copper HS and quietly lowered my temps 7 C. I got a XP2100 to replace my CPU and lowered my temps another 4 C with better performance. It is a Palamino version and as a side note came with a much better all aluminum cooler. I still use my Vantec, but this stock cooler looks like a OFZ Dominator (Those initial may be wrong) with an AMD fan. Impressive.

Vantec has two models of the 6040 the other is a 6040H with a higher speed fan (Noisier too).

If I were buying a new cooler today it would be the Vantec Aero with the TMD fan as mentioned by several others. Maybe not the coolest or quietest, but a good combination of the two. :)

[coyote]

OK, I'll add my to cents:

My research brought me to the following components to cool and quiet my athlon XP and case (with three harddrives):

- Thermaltake Volcano 7, because it had a variable fan speed based on temp. This helps the sound most of the time

- Paste was Arctic Silver II (before the III came out). I followed the directions to the letter. In fact I was so paranoid that I called them (or someone) to get a real handle on the amount of paste to apply to the die. This part stressed me out the most, since it was the first time.

- A good balance of pressure from within the case. I got some variable speed case fans (with speed controls), and I by turning down the speed on some of the fans and even turning some off, my case cooled better!? ... and not as noisey.

- The part that brough the cooling all together was a product called 2COOLPC. It is a cooling duct with a low rpm 90mm fan that blows right on the CPU area. I brought temps down 5 - 8 degrees C depending of room temp.

- Lastly, the sound was still an issue, so I bought a sound kit call Powersnooze, which cuts the sound in half. It contains three diffferent materials...some sound blocking and some sound absorbing.

Sometimes I wish I just went with a Pentium.

[Babulmiah]

The Zalman is active coolng, it uses a very quiet 9cm fan mounted using the PCI slot cover screw-holes.

I run an XP2100+ at about 39C~42C and the room temp is about 25C. The HSF is the pure copper version and I use the artic silver II.

[stevo_dave]

The Zalman is useless. I've had the all copper version on my 2100 and it was running at 50c.
which is no good when trying to overclock. Get yourself a Volcano 7+. all copper base and a 80mm fan which has 3 speed settings, 3000rm 4500rpm and 6000rpm, on 4500rpm my 2100 runs at 39c constant.
