sorry i meant 1.425
Could a scratched waterblock be affecting my temps.

Takes about half an hour per block. You can get by with 10 minutes though. It's worth it and makes them look all shiny.
To me it seems daft buying expensive watercooling kit and not lapping it. There's 3-8 degrees in it usually. And if yours is scratched then it could be sitting uneven.
Nah, it's not the water. Check for any kinks in the tubing though.
you are aware that many block mfrs including I believe EK bow the base of their blocks on purpose to provide added pressure to the centre of the IHS?
If you're going to lap anything it probably ought to be the cpu and I'd say only lap the block if you're also doing the cpu.
Either way unless its a whacking great scratch its not going to make 15+c difference in temps.
Having looked more into it.
Bowed > Flat for current Intel IHS - I don't know about i7s.
Flat > Bowed for current AMD IHS.
But I can't find anything which shows that a flat mirror finish is worse than an uneven bowed finish. The only thing I could go on is that a flat Apogee is roughly as much worse than a bowed Apogee as the reported gains from lapping are.
Last time I looked into it, some time ago, for my purposes (de-IHS Opteron) flat was better than bowed, which is why I'd forgotten all about bowing.

oh god yeah, ihs-less opty would be better flat or you'd probably risk crushing it..
The current blocks are bowed to make better contact with the core and to compensate for the natural concaved nature of intel IHS', I found when I lapped my IHS on my Q6600 and E6700 it knocked quite a lot off my load temps.
like 5-10c lots which is a heck of a lot.. not that it made any difference to my overclock!

Yep, my point is that 5-10 is what people report from lapping... so which is best? I'd say in a case where there's a scratch then lapping is a given.
However the bow in the block is usually caused by a larger o ring, which I believe Swiftech supply as an option with their Apogee blocks. By doing that people can choose between bowed or not. Although once it's been done I can't think how it could be undone, other than a hell of a lot of sanding.
I have no idea if EK bow them in advance, bow them at all, or supply o rings to bow.
