Computer Overheating? Help :)



bigmaddaz

bigmaddaz

Ok im running a

AMD 3200+
1GB DDR 400
128MB GEFORCE 5900XT
400W PSU

My computer recently has randomly being restarting... just been doing assignment then got media player playing music, word open and then web browsing and just resets.. the temp is idling around 53c and under pressure goes to about 55-56c is this too high? Ive just taken side of case off got big desktop fan blowing on it and its doing all the above at around 49c

Ive got a GIGABYTE cooling fan looks something like this

http://www.mwave.com/mwave/spechr/images/BA20662.jpg

The fan cost around £30ish so aint just a standard £5 one

My case has 2 fans on side , 1 fan on front and fans on PSU.

Anyone have any ideas?! water cooling the way forward !? Do these expensive thermaltake cases actually work ?! Ideally would like to make it run at around 49c without aving side of case off and desktop fan blowing cos makes hell of a noise.

any help about ruuning temps etc... or cooling :)

Cheers

Check to see if the cooling fins on the back of the heat sink aren't clogged up with dust, mine was getting hot, took the fan off and jammed a hoover in, and it's sorted now. Good luck mate

Thats pretty hot .

My rooms a constant 25 - 26 degrees ( don't ask, my mums fault lol )

My pc usually runs about 46 - 51 degrees , sometimes a little higher when the fans get clogged up .
So i installed one of these .Reduced the temp by hell of alot .

Do you have it set in your bios to turn off at high temps ??

As fatboy says , clean out the fins on your heatsink , clean all the fans of any sh*t on a regular basis . Do ya smoke ? This makes dust n sh*t stick to the fans .

All clean inside... had it all open a week or two ago.. hoovered inside carefully and used cotton woll buds. I cant change the settings in my BIOS... even under advanced bios settings when i press ctrl + f1 there is no options relating to that.

Those exahust system blowers any good? noisy?

that temp is ok for that spec cpu , the athlons tend to run hotter then other cpus
my system temp at min is 30 and cpu 48.

what i would recomend u check is the grfx card fan and if u have a main board fan for the fsb check that, ive just recently changed both of them on mine

other things it could be is software , try running a reg checker and adware remover

the other cause could be a faulty power supply this happend to me year back had a 20 quid one on when i was over loading it.

if its none of the above , try a fresh install , if it aint that , could be somet like a dry solder on main board

athlons run much hotter. Ive always had a problem, it runs at 90oC CPU sometimes. When it gets like that I just hoover out all the dust and really clear out the fans of dust. It does the job for a month or so.

thats not to hot to cause any stability issues but its still running to hot for an A64 especially if its a 13nm one.

you got enough thermal paste on the bottom of the cooler? try re-seating the cooler to make sure its on properly. you got any case fans (should have atleast one at the back blowing air out and one at the front sucking air in)

paying extra for a better case is well worth it, i went from a cheapo to an Antec Plusview II and it made a massive difference to my temperatures then i recently went to an Antec P180 and that made an even bigger difference!

It cooled mine down hell of alot , only a couple of quid and you wouldn't believe how much heat the kick out the back of your pc .
Just slot into a pci slot , molex connection , 2 mins of a job .
Give it a try , what do you have to lose ? Not as noisy as case fan .

athlons dont actually run much hotter, this was tue for the older ones but not for the A64s

an Athlon XP or 64 will get unstable when running at arround 70C so your CPU wouldnt last running at 90C so its likely your temperature sensors which are wrong (most are, some more than others) you could try updating to the latest bios to see if that helps as manufactuerers sometimes put fixes in for wrongly reading temp sensors

i personally wouldnt bother with
http://cgi.ebay.co.uk/PC-Exhaust-Sys...cmd ZViewItem
if yer guna source this type of fan look for this style
http://www.pcnation.com/PCNproductimages/418561.jpg

there not that power full , and there no point to them, as there near bottom of yer case and heat rises,

if yer that worried about the case been hot get some normal case fans and out em on side panels

most coses have slots for 1 - 2 fans at the front of the case,
http://www.over-clock.co.uk/acatalog/Case_Fans.html

i personally have a lian li case with 2 fans on the hds, 2 fans near cpu at back, 2 fans abover psu, 2 fans in the psu , fan on grfx card , and a uprated fan on the fsb.

So whats wrong with this fan ?? Like you say heat rises , but when the case is saturated with heat , these fans still reduce the inside temp .
Its reduced mine by about 3 - 4 degrees .

Only costs a couple of quid so its not alot of money if it works !

because the basic fan design isnt good , u cant clean them , and by the sounds of his case there is 2 fans behidn the cpu , and 1 fan maybe 2 on the psu , which would take care of the hot air .

the only time yer fan uve got is any good is if u need that bit of extra cooling near the grfx caras the face of the main chips on the gfx would be near the far , but nowadays the grfx cards have there own fan.

if u look on n e decent over clocking site they wont even stock the pci fans as there aint much point in them , best getting a hd cooler bay that takes up a 5.25" bay at the front of the case.

of just go extreme like i have in past and installed 12cm fans foceing air through the case.
owt after thats water cooling, which will prolly be on my next pc :D , if i ever decide to upgrade

Fans
CPU 2860rpm, variable depending on temp 30 atm
fsb fan 8036rpm
grfx fan 6490rpm

When you say nowt wrong with that case for cooling! Do you mean the one I got now or the thermaltake? i.e. is it worth me gettin the thermaltake or will I not notice a difference?

my amd 3000+ sits around the same temp

after being on all evening its currently sitting at a cosey 51*c
games make it go up to about 56*c but ive not had any problems with instability

if i put my exhaust blower on it seems to cool it down about 2*c as its right next to the gfx card and sucks out and hot air str8 away. pitty the thing is so noisy tho!

Another thing to look out for is putting too much thermal paste on the CPU, as I was saw a friend's PC when he couldn't figure out why it was overheating; the problem was he had like a huge amount of TIM on the heatsink. Too much can be just as bad as none, if not worse.

Oh and as far as watercooling is concerned, it's ace! I installed a Asetek CPU kit on my P4 3.4, and at full load i never goes over 37 degrees. I'm going to buy a waterblock for the Northbridge too, because I was so impressed. However it is risky, so unless you are sure about being able to fit it leak free, you may want to look at other options.

Yes it is but not for that reason. Think about it, even if you put too much on, provided the heatsink is touching the core, it will just squash it out and it will pour over the rest of the die/cpu packaging. That just makes a mess unless you are using arctic silver for the thermal compound and you may need to worry about conduction over the bridges on top of the cpu (amd only).

Also, thermaltake cases are not what you are suggesting them to be. Poor build quality which is why they are CHEAP. If you want a decent case get an Antec, Coolermaster etc and pay over £70. You get what you pay for with case design and quality.

My athlon 2500+ when was overclocked and read as a 3200+ still ran at 32c on air cooling only got up to 40c during heavy use.

Seems a little hot to me And you will find now that the hottest cpu's are the intels now.

Also the fan in your case putting air in would be better positioned round the back of the case extracting the hot air. Cool air in isnt as important as getting the hot air around the cpu out.

And putting too much thermalgrease on does cause overheating as it acts like a blanket it does get squeezed out but not enough.

You want the thinnest possible layer you can get its only there to fill the very small holes between the surface of the CPU and surface of the heatsink.

But your temps dont look that high what it could be however is you have an option set in your motherboard which restarts the comp when it hits a certain temp. If the graphics card isnt cooling as well it will also cause a restart if its getting to hot.

Avoid these PCI cooling fan things! yes they can make a slight difference if they are beside a hot running graphics card but even then you would be better with an Arctic Cooling VGA Silencer.

to much thermal paste is just as bad as having none you just want a fine coat.

also one thing to remember is too many fans can be bad, it causes too much turbulance and you end up with higher temperatures. most you want is 2 at the back blowing air out and 2 at the front sucking cool air in, possibly one at the top of the case blowing air out if your case supports it.

with a decent case with the cooling set up properly ive got an Athlon XP-Mobile 2500+ @ 2.6GHz running at 44C full load and my computers nearly silent :)

Your temps arent that great but shouldn't be causing these problems. Random resets can be caused by a variety of things, cpu, motherboard, memory and even power supply. If you haven't changed anything and it's started recently, then it could be that one of the components is failing. Run a memtest86 and see if it fails. If it does, try one stick of memory at a time to see if you can isolate the defective one. The motherbaord can also cause memtest failures. Try running prime95 to see if you can make it crash under load. It would be handy if you had another cpu to try. I also try to avoid generic brand power supplies, they're usually garbage.

This was not the results I found on that PC; at full load it would run averaging 80*C. After I cleaned the Heatsink contact surface and heatspreader and I applied a smaller amount of the same TIM, it instantly reduced to 60*C at full load.
Another problem with poorly applied TIM is that It can't trap air too, which is poor conductor of heat in comparison.

Ok... cleaned out pc today loads of dust in cpu fan and everywhere else, cleaned off paste of cpu and applied a paper thing layer... when I have case open and desktop fan blowing on it was idling about 47 degrees. Now with all the case back on it idles at 51 degrees, and im playing football manager and now its running at 56 degrees. In SpeedFan its showing a Fire symbol next to the 56 degrees. Where as before when the case was open with dektop fan I had media player playing, photoshop open, flash open, webpages open and was running at about 51 degrees.

My case has 120mm fan on front, 2x80mm fans on side, one blowing in and blowing out, then fan on back by power supply.

Any ideas?!

Also something to consider; the MB temperature readings are not always accurate. Sometimes they can be out by a long shot. See if there are new BIOS flashes for your mother board, they usually fix that kind of thing if there was a problem.

Front panel of case.. where there are plastic parts to pull out for cd roms etc... ive pulled one off and pushed metal out and now the temperature is running about 5-6 degrees less! seems to be working :)

The fans are in the wrong config big time.

Where the exhaust fan? You do not put a fan putting air in next to a fan pulling air out they will pretty much cancel each other out.

Best way have the 120mm putting air in have an exhaust at the back and on on the side nearest the cpu putting air in. Should knock a few degrees off.
