Since your swifty isn't the best low airflow cooler out there, and those XP's know how to heat up, I REALLY doubt your temperature numbers unless you have the case side off - I don't acheive temps anywhere that good with three L1As on my duron.
Actually the temps are about right. He's getting about a 0.5°/W, which corresponds pretty well with what I get with the MCX462-V
and a low flow 92mm fan.
One thing to remember, Silenx doesn't actually make
any of the things that they sell. They're just a relabeler, they buy the products wholesale, slap a Silenx label on them and then resell them at a mark-up. As for PK himself, well that's a long, long story, but its pretty clear that the guy has some issues. The "forum thing" they did wasn't sales reps, it was the owner of the company attempting to defraud potential customers and slander the companies that he's involved in a trademark dispute with.
