Hi guys and firstly let me say thanks for the informative posts here that have encouraged me to do my first overclocked and water cooled system. My system is a P5K-E/WiFi mobo and Q6600 and it is stable at 3.4ghz. I chose as a starter water cooling kit a Swiftech H20 120 Compact Kit mounted outside my case with a MCB-120 "Radbox". The whole kit and caboodle sits in a Lian-Li PC-60 PLUS Aluminium Midi-Tower Case. The case has 1x120mm fan and 1x80mm fan drawing air in and 1x120mm fan and 1x80mm fan exhausting air keeping everything gently cooled.
I'm currently running 380x9 to get 3.4ghz
My full system:
- Asus P5K-E/WiFi with BIOS 603
- Q6600 G0 SLACR
- Crucial Ballistix 2GB (2x1GB) DDR2 PC2-8500C5
- Lian-Li PC-60 PLUS Aluminium Midi-Tower Case
- Enermax Infiniti 720W EIN720AWT Modular PSU - Triple Quad
- XFX nVidia GeForce 8800GT Alpha Dog Edition 512MB
- Swiftech H20 120 Compact Kit with MCB-120 "Radbox"
- Arctic Silver 5
My load temps are quite high at around 75c and the highest FSB I can get with x9 multiplier is 385 for a stable system but then the core temps go up quite a bit. I am guessing there are two main problems but I'd like your opinions please on what I can do to increase my speed and decrease those temperatures.
What I suspect may be wrong in my system:
- The case is too small to allow air to flow freely being a mess of cables inside (I have 5 hdd's and 2 optical drives)
- The Swiftech H20 120 may not be good enough.
I am therefore considering swapping my case for a Lian-Li PC V2000B PLUS Full-Tower and the water cooling kit for a Swiftech H20-220 Compact Watercooling Kit or Swiftech H20-220 Apex "Ultra".
Any advice would be much appreciated guys.

The system ran stable with Prime95 but the core temps were approaching 80c and I bricked it
At 380x9 I ran Prime95 for 12 hours without a single failure. I ran it again for a short period to provide info on my system under load. Here is a pic:
