Ideal Fan Placement for Gaming PC?

[ghostops121]

Hello all,
I'm putting together a gaming PC, and initially I only had one fan on the rear. I quickly realized that this was insufficient, as my CPU temps got close to 100C under heavy load according to MSI afterburner (my GPU temps, however, were quite good) so I purchased and installed two more fans. My question is, what is the ideal fan placement for my case to lower CPU temp? The whole intake/exhaust equation has got me confused. I've created a crude not-quite-to-scale drawing of my current set up.

Forgive my poor paint skills.
Thanks for any help.

What CPU cooler do you have? Is it properly installed?

But for the other fans - in the front, out the back/top.

I'd move the top exhaust and make it the bottom intake since those drives are doing a good job of blocking the front intake. Plus, more intake than exhaust seems to reduce dust buildup.

Maybe the thermal compound is improperly applied?

If that is properly installed, the CPU should never approach the temp you are seeing. It has nothing to do with the case fans.

I think an actual picture of the case would work here.

Ok, sorry it took so long for me to get back, but I've found a problem. I got moswt of my parts from a friend's 1 yr old computer, and I never checked for damage. I just found this on the cpu.

Looks like some thermal compound came off. I still have some compound left, should I try to fill it back in?
Should I take this question to another board?

Badly installed thermal paste.

Clean it ALL off, on the CPU and the water block.
Reapply. Install.

Darn. Trying to get the block back onto the cpu was a mess, what an annoying problem.
Thanks for the help, I'll do as you say.
