Upgrading CPU: should I upgrade watercooling?

[StAndrew]

Currently run an X6800 at ~3.7, 1.45V and two 9800GTX+ cards with very nice temps (cards stay below 40C at load and CPU stays below 55C at load). Using the FuZion 2.0 and two MCW60's with the MCP 655, a 240 and 120 BIP GT Stealth rads. Im putting in my new Striker II Formula and Q6600 and plan on hitting ~3600 as well as overvolt my 9800's to ~900 core.

I suspect my above mentioned hardware wont be able to keep things as cool as before, but should get the job done resonably well. Any thoughts?

These chips run awfully hot!

I have my 965 @ 4.2 under a GTZ with its own 120.3 and temps still see mid 70s under load when HT is enabled. With HT disabled, I am able to drop my vcore a bit and the temps seem to stay in the low 60s under load.

give it a run and tell us the results...

my thoughts: you may want to upgrade those Radiators... say a 480 rad should be more than enough... or a set of MCR 320 & 220...

It would make things much cooler, no doubt. Ill see how this runs for now. Unfortunately, the way I have my setup, I cant really add any bigger rads (or thicker). I replaced my front mounted Swiftech 240 with the GTS as the Swiftech was sticking out too much to put the dust filters on my Thermaltake Armor. I dont want to drill holes for an external rad... I may try some stronger fans.
