Hang on, you meant there's only 1 fan inside your case, and it's the one shown in the picture, below the psu? :eek:
Haha yea, there were 2 initially, i placed one below the current one to drain out the heat, didnt really work though since i still had to play my games with the case open.

Ok, no surprises the PC is overheating then. Anyway if you were to install one two fans at the back, they should both be exhaust (blowing air out of case).

I believe there should be holes to install a few fans at the front, near the HDD cage. I think 2 intake fans in front and 2 exhaust fans behind should be sufficient, but it won't fix the dust issue in a convenient way. The new PC cases have dust filters near the fans that can be easily removed and washed without opening up the case, so that's probably what you want.

Anyway, 1 & 2 suggests that your CPU was overheating. To see check whether your heatsink is mounted properly/thermal paste is ok, download HWMonitor and prime95.
  1. Open your case and point a fan at your PC. Set it to a reasonable speed (lowest should do, unless your fan is going to spoil :s13:)
  2. Run HWMonitor, u should be able to see your CPU temps ("Intel blah blah") in realtime under "Value" column.
  3. Run prime95, click "just stress testing" if prompted, then "options" -> "torture test" -> "in place large FFTs".
  4. Watch your cpu temps shoot up then slowly climb for about 10min, then note the maximum. But if u see it going above 90degC, stop prime95 ("Test" -> "Stop") - u have a problem with heatsink mount or thermal paste.

Since you're using stock cooler, anything around or below 80degC should be fine.

Regarding the first time u went to get it fixed, did you ask the guy why he claims your gpu and motherboard are damaged? If he can't back his claims, then he's prolly bullsh!tting, so don't worry too much for now. :)

Problem.

1. Too little air getting into the case.
2. Too much heat generating within the case.
3. Too little fans to remove hot air from the case.
4. Overkill using GTX570 SLI to play DOTA 2 thus contributing unnecessary heat within the case.
5. Too much wire cluster within the case.

The cables are quite messy. Maybe u want to tidy it up so that it wont obstruct the airflow.

Hmm not much details though but i assume the GPU fan was slightly damaged as it was giving out some noise whenever i play high intensity games. As for the motherboard, it was the usb portion at the back since it was pretty obvious as i could it it bent down slightly than the usual horizontal position it was suppose to be. Haha i figured he gave me some bull**** as an excuse to get me to buy more stuff, thankfully all i got were new hard disks.
For the fan at the HDD slots, nah, not for this case, guess its time to go case shopping on payday.
Meanwhile I'll run the test tomorrow and update on my findings haha. Thanks for the help man!

Hi guys, sorry for the long absence, been busy with work, gotta fund an upgrade somehow haha. Like chong said, i did the check on the CPU heatsink and the result were that it hit above 90 at around 9min 30 sec, so i guess its a near pass?
So i think right now, the stock cooler isnt working as well as expected due to the poor airflow in my current case. I'm looking at changing it to something like Corsair Carbide Series Black 300, is it a good idea or is there any other recommendations do you guys think its better?

Alot with one simple water cooler(for long term), as a form of assurance so that i dont have to constantly check the temperature. Any suggestions on this?
Thanks for all the help so far, i've learnt quite a bit than i would have with blind research.

Hi I have sort of similar problems to you. My cpu can hit 90+ degree when I am running dota 2 and my fps is way too low for my newly built com.

Anyway, I think that for me the problem is with the heat sink. During installation of the gammax 300 series heat sink it took about half an hour because we had a hard time pushing the pins in. Also my hand accidentally touched the thermal paste quite abit came off on to my fingers does it matters alot?

If it is the cause of my problem, do I need I get some thermal grease? Or I can just spread the grease on the sink?
Sorry to hijack your thread :p

Thermal paste has to be extremely thin and cover the full surface area. Too thick and the temps will rise.

For mine the gammax 300 the thermal paste comes tgt when I buy it. I think after my finger touch it it doesn't cover the full surface.. Later will probably go home and take a picture of it to show you guys

Can use isopropyl alcohol to clean n remove the thermal compound. Then apply some arctic silver 5

You can change the cpu case if you want. If there is an empty slot in the case, what you could do is to add in some more fans. Of cause do take note the position of the fan whether it is an exhaust fan or intake fan.

Next if you think you have some money to spare, then probably just get a better heat sink. But when you get the new heat sink please remove the current thermal paste and reapply a new one. Artic silver will do.

Let us know whats the results you are getting and does it still shut down.

Was that test done with the side panel removed, and a household fan blowing into the case?
