hmm.. I really donno, are your hs/f on the CL Pro ones that's hold down by the 2 pin type thing?
on the Gillmont DDR it is, that's why the blue orb is perfect fit, I just removed those old pin, which is the hardest part on it, and turns out they use regular silicone compound, not the dry up hard to take off ones, so I just take alchol pads and cleaned the chip, reapplied some radioshark paste, and put on the BlOrb.
The whole thing took about 20 minutes, and most of it was spend on takeing out the old Gillmont pins.
If your CL uses the same 2 pin design, then you should be ok, just make sure when you pry out the pins on your old heatsink, you dont' scratch up any of the stuff around it, or excurt too much pressure on the board itself. Or next thing you know you'll hear a funny crack and your board is gone.
The blue Orb is very very good, but very very expensive. the front of the chip is cool, but the back is hot. I'm thinking about attaching the old heatsink/fan on to the back, but the back is bumpy.
