Temp too high?

I'll try and do the pics tonight when I get home.

Thanks to all for your advice. It is appreciated. I'm confident that I'll get the problem resolved with the help of MyBB members.

Only problem I see with buying it online is that shipping would be 25% of the price.

But maybe it is the best route. But I guess ultimately I'd also have to consider getting a new case...

Hi All,

Sorry for taking so long. Here are the pics I promised. Any further advice would be appreciated.

It is an Aopen case. I unfortunately do not have the model number:

I was mistaken regarding the case fans. The case has 2 positions for 8cm x 8cm fans in the back:

Would it be worth my while to just install a case fan? After playing Red Alert 3 a bit last night at 1920 x 1080 resolution the temp got up to 76 degrees. So i put a free standing fan on the box with the cover off and switched the PC off. At the moment it is idling aroun 50.
 
As a start it would be a good idea to install at least 1x 120mm fan at the rear of your case to extract hot air. Very simple to install yourself, just make sure it is installed the right war around and extracts! If this does not help, then go for the Thermaltake (etc) cooling system with the fan at the back. Is the space at the front of the case (underneath the hard drive) for a fan? Normally there is an intake fan there...
 
No space for an intake fan. How will I know whether it is the right way round?
 
There should be an arrow on the outer edge of the fan...

You can also look at the fan blades, the orientation dictates the direction it will blow/suck at just like a normal houshold fan.
 
Haha, I got frustrated as I just couldn't figure out the orientation of the fan. So guess what I did.

I lit a match. Burned it a bit to the middle so it would smoke nicely and held it next to the fan. :D Now I know which way it blows. :D

The bad news is that it has only made a marginal change to my temperature problem. :( I've ordered a TX2 from Sybriatic.
 
+1, with front intake fan and side panel fan and maybe even extractor fans on top of the case!!

Hi All,

I've upgraded my old PC. Took out the old mobo, cpu and hard drive and installed an Intel board, Q8200 and SATAII HDD. I've only got the PSU fan and CPU fan running in the box.

The BIOS reflects CPU temp as 30 degrees and the mobo temp as 73 degrees. I downloaded RealTemp and ran the stress test. The max temp was 76 degrees, with cool down after stress test down to 60 degrees. When I just switch on the PC the temp is 48 degrees with idling temp when browsing at 50 degrees.

I've gathered now that this might be a little too high. The case has some venting holes on the sides but no place to fit a fan. Here is where I need the advise.

1. Would it help if I just fir a fan to circulate air in the box some more?
2. Do I need to drill some holes on the side and install a extractor type fan on the side of the case?
3. Would an rear extractor fan work? (Like this)

Intel southbridges run hot - I believe that's your 70's temp. I've cured a few by putting a little fan directly on it. Try touching it to confirm.

Please remind me again which part would be the Southbridge. :D

Looking at the pics you posted it is located between your cpu & gfx card slot. That silver heatsink with the fins sticking up. Ram is just to the right of it.

That's the memory controller hub - northbridge - and which on most boards runs hotter than the I/O controller hub -southbridge. But it would seem on some intel boards - personally I've seen 5 or 6 - that southbridge is one hot little chip. Intel in their wisdom put a tiny heatsink on the thing, and a massive finned beast on the northbridge. They even know the things run so hot because if you use their own board monitoring software (Intel desktop utilities) they use different temp scales for these chips compared with the rest of the board.

My solution is to change the heatsink on the southbridge with something a little more realistic, and mount a little fan on top of that - I used a little thing from an old nvidia TNT 2 graphics card. You'll see the temps drop from the 60's and 70's to the mid 50's. You might battle if you have a large graphics card, but I see that thing in your case ain't so long so you should be alright.

NO FANS?!?!!? Get a new case! If your MB temps are 73 then there is NO air flow. Get a case with at least one intake and one exhaust fan... and what the other guys said, reseat the heatsink with a decent thermal compound, preferably arctic Silver 5

Lol it's common knowledge that all fans must be pointed inward ;) if you know how air dynamics work and cooling lose the exhaust

I beg to differ: Having one extra exhaust fan, mounted at the back below the psu, creates a negative pressure (vacuum) inside the case which naturally draws fresh cool air through, usually from down low at the front in most well-designed cases. In my experience this is usually the most efficient, not to mention the quietest, solution.
 
Oh on the contrary old chap. Google some studies done on this. :)
The "vacuum" a fan's vacuum is so small on a pc fan it is futile. Have fans blow all in making a pressure build up of cold air for heat to transfer too.

if air flows in---->pc------>out a low pressure of air vacuum is there but less heat is carried over.

------->pc<------- builds pressure making more cold for the heat to transfer too and the resulting pressure seeps out trough small openings.

Try this you will see drops in C

Of the dozens of systems I've built for myself and hundreds for others, I've found my setup usually works best, so I'll stick to it, thanks all the same. In a setup with an intake fan low down in front and exhaust high up at the rear, I try and regulate the front intake to run a little slower than the rear exhaust. This gives low temps as well as low noise. Having one of those side cover ducts directing air straight to the cpu is also a bonus, especially if it's adjustable in length and you can get it to sit right on top of the cpu fan.
