Temps abit too high?

They're not bad... but if it got any higher than mid 60's I would definately be concerned.

Its warm but its still okay your ambient temp should be pretty good at the moment in the UK. Thats an 83% overclock youve got there. Youre voltage is more than I would like for continuous use

1.55v is nothing to worry about, i run 1.65 on my q6600, but with a way bigger rad. then again, any 360 rad should be sufficient for that.
if i were you id try reseating, if that doesnt help, its already running as it should.

Wonder if i havent put enough thermal greese on the CPU.....Hmmm

dont worry, its quicly too much actually... a rice grain sized dab of paste is enough.

I always try 4 or 5 remounts, one every couple of weeks and then try to work back down to my lowest temp.

That gives you a little practice mounting your water block to, try to keep it nice and even as you tighten it up.

EDIT: Don't use your finger, use a razor blade or put your finger in a baggie.
