Simple problem, my HS/FAN isnt upto the job of cooling my CPU.

Internal Case Temp stable @ 36c
CPU under load over 53c causing blue screens & lockups.

Can anyone recommend an HeatSink/Fan for an
AMD XP (Barton) 3200 (400mhz fsb)

Thermaltake Volcano 7?

There is no reason your HSF should not be up to the job. Clean it down? Re-apply thermal paste? Or get a slow 120mm fan to pull the hot air out of the case...

Your internal case temp is pretty high. Even the most basic HSF combo will do the job providing the surrounding air is cool enough.

Try taking the side of case off and pointing a desk fan at the insides, stress the comp and check temps. If this helps add a couple of fans in increase air flow (remember you want a slightly negative flow of air in the case) - if you dont have the room, get the Dremel out.  :mrgreen:

I was wondering about the airflow, is that more of a vacum from fans sucking/pulling air out? Or higher pressure from fans blowing in?

better to have positive pressure in a case, because you ideally want to keep dust out.

If you have negative pressure (i.e. vacuum) then youll be sucking dirty dusty air in through every orifice.

Agreed, but for pure cooling its better (dont ask me for a link I read a very convincing article about it a few years ago, plus -ve has always worked better in my machines).

So, get a Dremel, and some intake filters  :mrgreen:

true if you have decent dust filters on your intake fans, but if not then it makes no difference as youre pulling dust in through those fans anyway.

Its long been known that if you only fit one fan (other than the HSF) then you get better temps if its an exhaust. I tested this extensively back in tha day and its been true with every computer Ive ever owned.

Only be that thinks 53 is a bit low for a CPU to start blue screening?

My CPU runs way hotter than that (cram packed shuttle) with no problems, I had my old AMD XP chip running at 92C for most of its 3 year life and that only died because i was an idiot and didnt put the HSF back on properly

92C???   WOW, never seen a CPU stable over 70C!

It might not specifically be the CPU, might be a component near it which is failing because of the heat its producing.

Think its something to do with lower air pressure equals lower air temperature.

Agree with that too, might be memory or a host of other issues.

Northbridge overheating? I had that on my last mobo when the heatsink wasnt properly attached. Luckily before actually bluescreening  it did random things like popping sounds from the speakers, giving me time to shut down

aye Id guess dead north bridge fan, unless its a passive like.

the case temp is measured from a point on the motherboard so might be artificially high if a overheating component is affecting it.

other major one is GFX card, although 9/10 it only shows up as a crash in games.

53 will most likely be socket temp, not the die temp which could be another 10 - 15 degrees higher worst case ? close to the 70 danger zone.
download Speedfan, if it can read the core temp and / or other temps, it will do.


only other thing, check your main capacitors round the processor / motherboard.
They may have started to bulge, if they have then the caps are dead and will need replacing.
 

:)check for any fan sped control in the bios too.... something that will chance fan speeds depending on CPU temp... the desired CPU temp could be too high so the fan doesent kick in 100% untill 80C etc....

and dio with what everyone else said, case cooling, case cooling, case cooling.... you should be able to easily nock 10C off your case temp which should drop your CPU temp 10C or more too

remember... cold in at the bottom, hot out at the top

The system in Question is:

- AMD Barton XP (2100mhz actual)
- Antec P180 case
- Asus (Via KT7)
- 1GB Corsair PC3200
- nVIDIA (PNY) GeForce 7600 GS 256mb AGP
- 2x70GB Seagate Barracuda SATA (Raid0) [ Installed in thermally isolated Bay]

Large Passive Northbridge, cooled by exhaust from CPU HS/FAN (also cooling from the rear exhuast).

Case fans has:
2x120mm Exhuast Fans, (one above the other directly behind the CPU)
1x120mm Input (Filtered) Fan on front of case.
1x120mm Input (Filtered) Fan for the HDD/PSU bay

- Case internal 25c Idle BIOS reading on first boot.

The Speedfan readings:
- Case internal 25/27c Idle

- HDD/PSU Stable around 27c under load (HDD Temps)

- CPU Idle 40c
- CPU Load (Test using Toast ) 49c ~
- CPU Load (Quake III) Stable & doesnt lockup.
- CPU Load (Joint Operations) Stable & doesnt lockup.

- CPU Load (Company of Heroes) 53c + Figure from BIOS on reboot, immediately after BlueScreen lockup.

- Taking the side panel off doesnt change results, in fact there is less directed airflow over the motherboard. Company of Heroes still locks up and CPU Temps are the same.
