I tried putting on my Thermoengine last night, and I almost fvcked up my Core and my IWill. The thermo engine is a beast when it comes to putting it on. I feel like a wimp, but this will have been my first heatsink and I dont wanna screw anything up . Just thought I'd let you guys know. Thanks for all your help, I'm gonna run it buy a local computer store today or tommorow and have them put it on. My hands are just way too shaky to put that beast on.
