They seem fine to be, you got to remember that a quad core is 2xdual cores.
1st dual core -core0 & core1
2nd dual core - core2 & core3
Its like having two e6600's under the hood!
Temps are fine, my Q6600 idle is: 38,38,39,39 (more or less).
100% stress Prime 95 maxes out at about 50 degees on each core and doesnt go much higher.
I runnin a q6600 @ 3ghz, FSB 333, vCore 1.2, memory 5:8 (PC8500) and is stable on prime for 6hours.
I found that when i was running my CPU at stock, i could lower the vcore and it would still run stable! When you have some spare time, just start tweeking it! Your vcore (as i found) will most probably be set on auto, so find your VID out and set it as that in your bios. From here run prime for about an hour, if it crashes normally means unstable and needs abit more vcore. But if its goin strong, lower tht vcore a little bit more untill the system crashes within that 1st hour. Keep going with that process, i know at stock with mine, i had a vcore of 1.18! It would boot and run prime for 6 hours no problems!
I have an arctic freezer 7 pro, £15ish in the UK. When i first had it, my CPU was idling at 55ish degrees each core, now that ive tweaked the vcore and its properly bedded in, as you can see its a pretty nifty cooler. Probably not the best, but good for light oc's.
Ill throw sum screens up when i get my PSU back (Being RMA'ed /RAGE)
