Confused by lots of Thermalright numbers

What are the performances of the following heatsinks? I was looking at the Aero 7+ because of the wacky design, but I realise that it may not be a substitute for sheer mass of copper.

What are the thermal resistances of these heatsinks? I'm a bit confused with all the nomenclature, and I know that price is not necessarily translated to performance.

SK-7 £16.45
SLK-800A?? (U version seems excessive) £34.08
SLK-900U £44.65

Aero 7+ £30.55

Since I will be buying my shiny new Tbred B soon (XP1800 DLT3C 0307VPMW wheee) I need a decent HS - got a fan already, jury rigged to the 92mm slot in the back.

Look here for their rankings. They're all quite closely drawn, and will all easily outperform the Coolermaster.

lol I really should read the front pages more...

tnx


SK7 it is then. Cheapest of the lot and only 12% more thermal resistance.

I am going to be buying the SLK-900U from the same store real soon!

w00t for england

How about the slk-700? Cheaper than the rest of the SLK's, and almost the same performance.
