I have two GlobalWin Heatsinks in my two machines, the WBK38 and the FOP38. All the reviews I have read show the WBK38 to perform slightly better. This does not appear to be the case for me, however.
I have hacked both heatsinks to accept an ADDA HighOutput fan (39 cfm, very quiet). Bot processors are running at roughly the same speed (clocked the 1120 down to 1050 to compare), however the one with the FOP38 is running much cooler than the one with the WBK38. Both are decently lapped, both are properly attached to the SAME motherboard, and the FOP38 outperforms the WBK by several degrees Farenheit. While my one processor idles with the WBK38 idles around 82 F, the other idles around 77 F (this is after using WPCredit to enable the Asus boards to idle the CPU properly).
These temps are taken using a heatsensor which has been taped on to the bottom of the heatsink (didn't feel like going to the serious hassle of boring holes). That said, both sensors are about the same distance from the processor core (as close as I could possibly make it, without being concerned about it actually touching the core or damaging it during heatsink attachment). If anything the WBK sensor is slightly further away (because the heatsink base is larger).
Now, they are not the same heatsink design, so it's possible that the temp sensor reads higher on the WBK bottom, but the WBK is actually working better. It's also possible that the WBK just sucks, or at least doesn't work as well with the 80mm fan "hack". Please note that I am comparing idle temps...most reviews compare underload temps, so it is possible that the WBK actually cools better under load but cools more poorly at idle (I guess that would be a fair trade-off?).
Anyway, if anyone can explain this phenomenon to me, I would greatly appreciate it. I'll update later with under load temps. Also, please note that I experienced lower temps with the FOP when it was on the motherboard which now has the WBK, so that would seem to rule out different calibrations in the two boards' heat sensors.
