I just installed my core 2 quad and the temp is around 55 c to 57 c. Is this a good temp. I have a themaltake v1 fan. Is there any other better fans to bring the temp down to like mid 40's

That's not a bad temp but it could be lower. You could get a Zalman heatsink/fan (hsf), i have found them to be very effective.

Google for reviews if you want, to find one that will reduce your temp the most

I run the same processor (Q6600). I run a Zalman with a 92mm fan. My idle temps are 40-44 C. When I'm operating a few applications is's still no more than 49-50. When I run the 20% O.C. and get a few apps. going it runs around 55-56 tops. I game @ 10% O.C. and it approaches 62 C. (tops). Mine is a B-3 model.

it also matter what Stepping ur proccesor uses im guessin that
acacia666avenue uses a B3 stepping and that
pdyckman@comcas is using a G0 stepping proccesor
there are difrent revisions on the Q6600 usualy the G0 stepping ones
run cooler

yea mine has b3 core stepping. i will research the zalamn cpu coolers. Thanks

I think both Thermalright Ultra 120 and Scythe Ninja are better than the zalmans..and both give you the option to on your own select the fan you like.

Those temps are alright. I got the asus silent night and my idle temps are 33 and max at 37

pdyckman@comcas 's processor has the B-3 Stepping. He said it in his post.
