IS that without being lapped? If so thats an absolutely awesome finish, but if its been polished, then you've done a bad thing...

sorry if it wasn't clear. It is lapped :)
 
The bottom on my Ninja is pretty ridgey, what is the realistic difference in temps before and after lapping? My cores don't exceed 50 degrees.

I don't know, depending on how bad it is but it will reduce the C/W resistance number which = lower temps hopefully!

Im going to be lapping my Tuniq Tower 120 :D

I think he means it looks too shiny to be a simple lapping. If you're lapping properly, all the way down to the tiny grits you might get it that shiny (no personal experience, so I dunno). silentphoenix is implying that you've added something else to polish it up, which is going to make it worse at transferring heat. Ideally, lap away metal until it's as smooth as possible (not necessarily shiny) and add tec to fill any remaining space.

There was a really pedantic thread a while back about how to lap "properly"...

No - This has not been polished at all - It was lapped down all the way to 2000 grit paper and then wiped off with my cotton T-Shirt ;)

I haven't tested it fully yet, so I cannot tell you how much temps have come down..... but as Tesco's say... 'Every Little Helps' :)
 
In that case mate that's an awesome result (assuming you've lapped it flat :p ). Should take a few degrees off I would have thought. I guess you'll only need the tiniest bit of arctic silver in there.

Lol.. osrry for not making sense before, but the first sentance should read "Is that finish without being polished"...

... and it seems so - gratz! IT would be interesting if you posted some 'before and after' temps :)

Just out of interest, what grit did you start off with, and how did you progress to 2000?
 
600, 800, 1000, 1500 and then 2000.

And it was done on a piece of glass. (photo frame glass to be exact) lol
 
I ordered the paper from a very popular auction site.

I didn't like the haldfors paper, as it wasn't very good quality and tore easily.

You have to use '3M' paper ;)
 
Good link I'll buy from there next time.

I ended up getting up to 1500 grit from Halfords and set on my P5W DH's heatsinks. The northbridge took me at least 30 mins to get down to a flat surface with 600 grit, it was as curved as my ass! :eek:

No mirror finish but the temperature went down 4c ;)
 
Wait...so how much of a difference does lapping actually make in terms of real world temperatures?

I've never lapped any of my HSFs....but am always open to new things :)
