Overheating??

[RAF92_Warhawk]

Hey guys,

Today my computer kept shutting down when playing bf2. I checked my temps. and my CPU was 40C and GPU was 70C. This kind of confused me because they seemed pretty normal to me. So I started BF2 up again and boom, computer shuts off again, and again. So I takeoff the side of my case and my psu is HOT. Its an "nspire" 450W psu. I'm guessing that is what caused the computer shutoffs. Is this just from poor airflow in the entire case?

Re: Overheating??

Very possibly due to your crappy PSU. nspire makes pure ****. Replace it.

Re: Overheating??

I don't really have any case fans though... that could probably be a problem

Edit: Would it be better to have my powerful fan as an exhaust fan and my weak fan as an intake fan or vice versa?

Re: Overheating??

For proper circulation you almost want a bit of a vacume so small intake bigger out. This help airflow throughout the case, I don't know **** about pc's but I do know about moving unwanted warm air. ;p

Side vents are great too but ideally to get rid of hot air you should have more going out than in as it makes the air rush by components faster bleeding off heat. The same principal applies to lift in aircraft and many other things requiring airflow just to provide evidence agaist people who know way more about computers than me.

This also means you do need to create a proper channel for the air to rush through.

I thought you always would want to create more pressure inside the case, so you would have more air going in then out. Thats what I hear a lot.

Re: Overheating??

it's about positive airflow.

Positive airflow is when you get more air movin' through the case, so the pressure is greater inside than the pressure outside.

If it is negative, you have very little air moving through the case.

The greater the airflow the better. Hot air is taken out of the case, and replaced with cooler/colder air, which can heat up a lot more and take more heat out of the computer, and away for the parts.

The less the airflow (creating a "vacum" so to speak), means hot air is getting recirculated. The already hot air is hot, so it can't get any hotter. Heat isn't taken away from the computer parts, which means the parts have to take the heat. That leads to parts overheating and shutting down.

having big intake small exhuast means hot air can't get out.

having small intake big exhaust means air is being forced into the case, which can be hard on fans, but you are creating more air flow.

Best thing to do is have 2 fans of equal sizes. 1 intake 1 exhaust. If you can't do that, then say 1 120mm intake 2 80mm exhaust.

Re: Overheating??

Its quite possible that your PSU might be over taxed or may need a good clean. So i'd check the PSU fan(s) and make sure that no dirt is present. System shutdowns are sometimes caused by overheating CPU's or failing PSU.

If no dirt is present on both then i think your PSU may need replacing.

Re: Overheating??

Its less than a half a year old though, maybe 3-4 months old....

This is pretty much the same as the one I have...

Funny that when you grow pot if you don't create that 'vacume' the plants overheat and lack in co2 as you're not getting enough air transfer. The same applies to this, if you have more going out than in and have internal fans for circulation the air gets moved about faster thus getting rid of heat faster.

I could be wrong this is just for discussion and if someone can post proof otherwise I'll just shut up.

Re: Overheating??

Sounds like your PSU is about to take a crap on you. This is hard on your drives and stuff, so you should really replace it ASAP. Get a good one with two fans at least.

Re: Overheating??

I only posted the theory I learned in fire school, and applied to computers.

Next time a house burns I'll apply your theory, and watch it burn quick.

Re: Overheating??

I took the side off the case so it should be fine now. I don't really know why there is so much heat in my case though. Ever since I got my X850XT the air coming out of one of the exhuast fans is so much hotter. My Vid. card has a special exhaust system so I don't know why it would be heating my case up so much.

Edit: after playing BF2 for at least an hour without the side of my case on, my PSU was MUCH cooler than when the side was on... Obviously I need to improve overall airflow in the case.

Re: Overheating??

i have a vibration that increases when i play, and i can't find it. it sounds as if my cpu fan harmonically resonates making it worse. it's not that bad, but i've removed the board several times and reset it into the case with no luck. i never can find the vibration though, because if i attempt to take the side cover off it goes away. it messes the rpm's of the fan when i disturb the case. moving my computer overall messes with this resonating sound that causes the vibration at it's gaming rpm. i know this vibration causes the internal temp to rise slightly. honestly though, i think the vibration would quit if i could drop the air's temp inside the case.

when i am just browsing, general gaming seems to be all it takes. usually a lil nudge on the case will quieten it for a little while.

if i had to explain it i would say my board is heating up and pushing/vibrating against it's risers, which might be the noise i am hearing.

i am going to look for an arctic cooler for my video card, and see if that helps.

i routinely take an air compressor to it cleaning it free from dust.
