Recently made a new budget rig for my occasional gaming and video editing, almost all the parts are brand new, exempting the case which was recycled from my last build.

Most temperatures are in the 'okay' zone under light load or on idle, the room ambient temperatures are usually 30-ish Celsius, HWmonitor reports that on average CPU temps are around 45-50, hard drive on the 45 zone, GPU at around 45 and case temps are around ~40

When under load though, say playing Crysis, it gets really hot, as in touching just the case makes you feel the warmth.

EVGA Precision shows drops in framerate playing Crysis 1, it only averages around 30fps at highest settings (I repeat, this is Crysis 1) There is no overclocking, voltage tweaking whatsoever involved in my build. Under load the GPU is persistent at 99-102 celsius, hard drive at 46C, and CPU at the 50+ mark. Plus even on earphones I could hear the roar of my GPU fan.

It's been at it since I actually built it, already reseated and reapplied thermal paste twice on my GPU. It never crashes though, it just stays at those temps as long as the game is open.

So my main culprit now is the case and GPU. Just to describe the specs:
- CPU: Intel Pentium G3260 (yes that is a Pentium dual core, got it because it's $65 as compared to an i3 of being at the $100+ mark)
- GPU: ECS GTX 560 (Second hand, bought it off a local trading website)
- Board: MSI H81M-P33
- RAM: 2x4GB Kingston DDR3 1333MHz
- HDD: WD Blue 1TB
- PSU: 450W switching power supply
- Case: Neutron Fit 281 mATX (quite small and it only has 1 80mm fan, so that's that.)

Bottomline: GPU is second hand but temps are outrageous at 100+ under load. Case only has 1 80mm fan on top and case is really small.

Tips to make it cooler? and could anything be wrong with my parts? maybe I'm doing something wrong?
Thanks
 
Solution
Tiny case, unknown PSU, 1 fan.

Thats your answer. Get a bigger case with more fans, also the GTX 560 recommends a 520w PSU, 450 could be fine if its really good quality, but underpowering it can cause problems as well.
