Cooling help

[Pyong Kawaguchi]

I'm starting to think that If I dont do anything sooner, problems will occur
So here is the situation
I am installing gears of war pc (very cpu intensive install :S)
and My pc is getting really hot, it also gets really hot when its running games.
Temperatures
CPU:
Diode 1: 78*c
Internal: 52*C
Diode 2: 49*c

Fan speeds
Fan 1: 4408rpm
Fan 2: 2200rpm
Fan 3: 2500rpm (according to hwmonitor, max speed is 5123, how do I set it higher???)

Gpu temp : 82*c
HDD1 temp: 58*c
HDD2 Temp: 51*c

What should I do guys, Buy better fans?
Buy a new case?
Buy water cooling?
Buy a fish tank and use mineral oil?
Any help is appreciated, thanks in advance :)

I have a quad core, and over 72C is a no no. It's not just going to kill over and die, but it isn't great. What gets me about your post is the massive difference in heat between the diodes. Seriously, what is up with that. One of my cores runs 10C hotter than the rest under load, but nothing like yours.

Edit: Pentium D quad core? Wat.

[Pyong Kawaguchi]

Its a Pentium D with 2 physical processors, 4 logical processors
