Major heat troubles

[Fweddy]

How hot would you reckon an AthlonXP 3200 underclocked to run at 1.1ghz on a gigabyte ga7n400pro with a zalman flower cooler would run at? With the side of the case off and two additional fans to help it? Go on, guess..

70 degrees according to the motherboard! 70 fucking degrees! With the cpu running at its proper speed that goes up to 100 in about 5 seconds and then everything shuts down.

Why is this? What can I do? Help me please!

Is your HSF on correctly? try taking it off and putting it on again. How much thermal paste did you use, and what kind?

Also, cases are designed for air flow, mine runs a lot cooler with the sides on, since air is coming from the front over the components and out the back rather than just coming in the side and out the back.

 

[Fweddy]

I'm almost certain the heatsink is on correctly. I'll try putting it on again tomorrow to see if that helps. As for thermal paste, I used arctic silver 5, and used about the amount the site says to.

I've learnt from experience my case is cooler with the side off.

 

[TdC]

you sure your heatsink is rated to your cpu Fwed matey? tbh, taking it off and putting it back on again seem a good idea. you'd not be the first with a bubble between the hs/core.

 

[Stimpy]

I could be completely wrong about this but I think Zalman flowers are only recommended to use on upto a AthlonXP 3000, it's quite possible your Zalman just isn't up to the job.

 

[SawTooTH]

Unless the Zalman says so I agree. It probably isnt up to the job.
Does it have a fan or are you trying to passively cool it?

Sorry, i've been using the Zalman flower on my 3200+ for over a year and it's absolutely fine and well within limits - just need to correct you all there .

However, one thing i've noticed is that because the Zalman flower sits side on to the processor, over time it doesn't quite make as good a contact as when you first put it on. Additionally, i've found arctic silver tends to be less effective over time and it needs reapplied for it to work effectively.

Take the heatsink off, re-apply the thermal paste, re-fit the heatsink and see if that sorts things out. Also double check your CPU voltage is at default (1.656v for the 3200+ iirc).

There are 5 different types of Zalman flowers for AMD though.

Also has it ever cooled the cpu properly and this probem has just occured over time or is this a brand new setup?

 

[old.user4556]

Fair point, but the one i have is this one and it does state a 2800+ maximum CPU but it can be used on the 3200+ without any problems.

The only version that goes up to 3000+ is the plus which appears to only have a faster fan speed.

Which model do you have Fweddy?

cpu maybe nacked. my 2400xp ran hot as a mofo untill one day it burnt out. it was running around 47c just from boot up. the h/s was on correct because i took it on and off a few times to double check.

 

[Fweddy]

Cpu and heatsink are both brand new. I have the AMD / PIII Flower Cooler CNPS6000-CU (The second one down). The fan is running at max speed.

Stupid thing. I'm going to log off now and try putting the HS on again, and if that doesn't work I'll make my own cpu out of some drawing pins and a fridge magnet.

Thanks for all your replies!

 

[Fweddy]

Current cpu temp = 45!

Spunking more arctic silver on the cpu and putting the heatsink on again worked! I just have to see what kind of temp I get when I put it upto the clockspeed its supposed to run at, instead of half that. Fingers crossed guys.

 

[TdC]

good lad! crank it up then!!

 

[Honza]

What can I do? Help me please!

Tons and tons of AMD cpus do this and AMD manufacturing does not consider it product failure so you simply have bad luck.. :-( Happend to me one one pc I was building - put amd there and it started heating like mad. So I tried other amd and it worked fine.

Having very bad experience with stability and heat output of AMD cpus, company where I was building computers stopped building AMD based computers. Since then everything is fine.

What can you do? Buy true processor, not central heating

Hmmm... do I spot an Intel fanboi? If you want central heating get a nice new prescott!

I have had about 8 AMD processors (from the Athlon days), and about 6 Intel ones (from pentium 2 up), and the AMD's have lasted better than the Intels (1 dead AMD vs. 2 dead Intels).

Hehehe, that's exactly what I thought when i read his post .

Yes, prescott is central heating too. Loosing heat is as high as at AMDs, shame for Intel since it has less microns technology.

You were truly lucky fella for AMDs. But still, if you read forums, you can hardly find 'summer overheating' etc. with Intels (thanks to Prescott is not spread out yet I think)

Hmmm... do I spot an Intel fanboi?

Hmm, yes and no. Truly, for pure 100% gaming computer AMD is better cpu (even though the difference is quite little - beware of AMD pentium rating because since newer P4 lines it does not correspond much (see tomshardware and others)).
For working stations (video editing, music, software development etc. etc.) Intel is incomparable number 1 (very probably thanks to HT technology since when you turn it off, performance differences are only about +10% for Intel). Also, me and my friend were testing DVD (2 layers -> 4,7 GB 1 layer dvd recompression). We used same software (Pinnacle something, not sure what exactly). Suprisingly, my computer (2,4 GHz HT Intel) was 10 minutes faster than my friend's (Athlon XP 2800+). But what suprised us both, quality of output DVD was different! While picture on AMD started look a bit oversharpened, Intel slightly fainted colours but kept sharpness more or less untouched. When compared on a few frames we agreed that output signal is more comfortable for eyes on Intel, but truly, the difference in quality is small - without comparing you wouldn't notice it.

So my conclusion: For 100% gaming only -> go for AMD, for 'multiusage' computer go for Intel (ofc Office and Adobe Photoshop are not considered to be any threat to both manufacturers so does not matter).

For cooling: Imho manufacturers of cases, cpus etc etc. should finally stop making more or less noisy coolers and go for different cooling system - probably Peltier's cooler + water circuit through whole case components imho. Yes, you can get it nowadays already, but $$$.

Intels have been putting out as much heat as AMD for years (since the P4 came out - P3 was the last truely low power chip). The reason you see less issues is because intels will slow down if they overheat whereas AMDs will just crash.

I'm puzzled. If heat is such a problem, why not buy a small beer fridge, build the pc into that, and modify the door to allow 5.25inch slots? That way, you could have a mega cool pc, with no fans or anything, and beer on fucking tap!

 

[Danya]

The fridge would die within days - fridges aren't designed for continuous heat loads, especially not small beer fridges.

 

[TdC]

however...there are cases to be had that use fridge technology and are reputed to cool one's CPU to below 0C. in fact, I nearly bought one myself last year, only to be put off by how ridiculously priced they are

the problem isnt realy the cooling tech
The main problem is making sure there is no watter condens forming on the cooled components.

and to a lesser extend making sure the cooled components dont physically break due to termal stress (it doesnt take a big fracture to ruin a 0.13 micron chip)


edit (I wouldnt mind one of these but at a listed price of $820 idd have to sell both kedneys

 

[TdC]

In order to actively protect from condensation forming around the evaporator head, Asetek provides heating elements for the clamshell and back of the CPU socket.

so they cool the inside and heat the outside (slightly) to prevent condensation. the article's writer manages a 1GHz overclock on two different P4 chips. I'm impressed. too bad the thing costs 1k eur eh? :/

actualy just found thios shop

dont supose anyone could spot me about 3k euro for my new machine ?
