ok here is my system spec:
AMD64 3800+
2GB ram
600watt PSU with duel fans
1x DVD/RW
1X CR/RW
1x floppy
Radeon 9700 pro graphics
AV8 mobo
1x 120GB HDD (IDE)
1x 40GB HDD (IDE)
sound blaster extigy sound card
2x HDD coolers (each with 2 40mm fans so 4 40mm fans)
3x 80mm fans
1x 120mm fan (high proformance)
standed AMD heatsink

it also has a new fairly big tower (it was a limmited edition thou on ebuyer not on sale no more) for good airflow and wires are neatly tied back away for airflow.

problem is in games im getting tempratures of 76C+
which is unacceptable this is now summer is here

i used to have watr cooling but scraped it when i bougth my new mobo + CPU

but i did buy a XP-120 heatsink + highist 120mm fan i could buy for it.. but it didnt fit on my AV8 mobo.. so ended up settling for standed AMD heatsink..

the processor is not overclocked and i dont se why with all my coolign im overheating.. my PC has been set up and workign fine for 1 and half months now buit with the warm weather now its getting bad..

how can i fix this.. and BTW im limited on budget of around £30 atm.. (still strraped for cash from when i did my major upgrade nearly 2 months ago being a student and all.

so throw yoru ideas at me :tazz:

(meanwhile my server pc havign only a AMD 2800+ STANDED HEATSINK and one fan.. dosnt over heat or get that warm.. hmmmm)

Is the case inside itself getting around 76C?- what type of product do you have inbetween the heatsink and the processer and did you cover the entire processer with any heatsink compound?

are any of your fans blowing air out of the back of the case? they can't all be blowing inside that'd be just blowing the hot air right back on the cpu.

my 120mm fan is blowing out at the back.. which is because my PSU blows out at the back (and well i dont want it sucking in warm air...)

my side panel fans and fround fans suck air in to get nice airflow..

what is the asus star ICE heatsink like? will it help?

Its huge and might damage your mobo, but if you have a xp-120 i have a friend who couldnt get his on either by very carefully bending some of the mosfets he was able to get his on(mind you he takes his case coolin seriously only do it if you think you can manage it safely). There are good reviews on the arctic cooling freezer 64 if you are on a budget. It seems quite unusual as the amd pib heatsink is a pretty good one in itself you may have a slightly duffed one.

Actually, come to think about it if youre side fan blows in and your heatsink blows out the two of them might be causing an airflow problem: set you side fan to blow out or your heatsink fan to suck in air see if that helps.

Hi,

there are known issues with that board and the reported temps from bios/software readouts, if the computer is stable I would not worry about it.

If you are still concerned you could purchase a therometer and place its sensor near the base of the heatsink to get a better cpu temp

heres a review from custompc

Akasa AK913
COMPANY: Akasa PRICE: £25inc VAT
RATING: ISSUE: 20 DATE: Apr 05

Verdict: One of the best HSFs ever designed


The AK913 is Akasa's first attempt at making a heatsink with heatpipes and the company has managed to hit the nail on the head right from the off.

Instead of having lots of little heatpipes impregnated in the heatsink, the AK913 has a single huge heatpipe that connects directly to the CPU heatspreader. Around the heatpipe are rows of aluminium fins, which are cooled by an 80mm fan. It's even possible to mount a second 80mm fan in a push-pull configuration on the opposite side of the fins to further improve airflow.

However, what really sets the AK913 apart from other HSF tower designs is its excellent build quality. The solid aluminium base screws into the standard CPU mounting bracket to hold the tower in place, so the AK913 doesn't rock about and cause the heatpipe to lose contact with the CPU's heatspreader.

Fan speed can be adjusted between 2,000rpm and 4,000rpm by the supplied rheostat. Our test CPU ran 17C cooler with the fan running at 4,000rpm, and 13ûC cooler at 2,000rpm, both of which are superb results.

The AK913 is well-built and easy to install, has a variable-speed fan and offers superb cooling performance, even at low speeds.

Thats a good cooler, a better one than the asus star ice i was in a local pc shop a couple of weeks ago and saw one. The thing was massive pictures you see make it look small but it is huge the size of a rugby ball almost just not quite as long and it weighs an absolute tonne.

But if you try you could probably manage to get that xp-120 on, although you should have tried to exchange it for an xp-90 at the time.

Hi all
I have seen this in more then one post on overheating on AMD chips.
Amd recommends that you use thermal pad NOT thermal paste. I have used the pads on all the AMD systems I have built and never had a overheat problem. thats about 30 systems in the last year. here is the link to the AMD Processor and Heatsink Installation page on there site. CLICK HERE
