Question about cooling Core 2 Quad Q9650

Hi!

My computer specs are in the sig.
When the price of Q9650 drops significantly I plan to upgrade my P5B Deluxe with it (replacing my current E6600).
Currently, the E6600 is being cooled by Scythe Ninja SCNJ-1000, this one:

Will this cooler be enough for Q9650 considering it's a 2->4 cores upgrade and 2.4->3,00GHz?

If it helps, I've just upgraded my E6700 to the Q9550 (which should have simular heat profiles to the Q9650).

I've got the same heatsink and with the stock fan (1200rpm) I've got fully loaded temps of 53c 48c 52c 52c across the cores. I'm also overclocked to 3.4GHz.

So you'll have nooooooo problem!

Hi, I upgraded from E6600 to a Q9400 and I think the Quad is cooler than the E! At least with the E6600 @ 9x333 = 3GHz I got similar temps under load to what the Q9400 @ 8x400 = 3.2GHz gets with the same cooler. (BTF-90 "butterfly") With Folding@home SMP load I can easily keep the CPU temps 50-60Â°C. Your Ninja should be better still.

Maybe of further interest to you is I have an Asus P5B-E Plus motherboard that is very closely related to yours, so Q9xxx CPU should work fine. I believe it's basically the same PCB but mine doesn't have the 2nd PCIe x16 or the fancy heatpipe cooler and possibly other things. It does have it's own BIOS and was supposedly a super-overclockable motherboard.
With the E6600 on 6x multiplier and old BIOS I could benchmark upto around 533MHz FSB. Newer BIOS seamed to limit to ~400MHz with the E6600.
I have to have newest BIOS to support the Q9400 CPU and it seams pretty much 24/7 stable with sane voltages @ 8x400=3.2GHz. I can get it to go further but not very stable and not bothered to try tuning for that last bit.
Good luck, Seb
