ThermalTake V1-Ultra CPU Heatsink


Installation & testing

Thermaltake has taken a different approach to installation than most third-party vendors.  Most vendors require that you install mounting hardware to the underside of your motherboard.  While this certainly makes the installation much more reliable, many enthusiasts are not so enthusiastic about removing their motherboard to try out a new heatsink.

Thermaltake’s V1 uses the same installation method of Intel’s OEM heatsinks.  There are four plastic pegs that must be inserted through mounting holes on your motherboard.  Pressing down on the pins pushes prongs at the end to spring open, making it impossible to retract through the motherboard holes.  The black pegs are then twisted to lock them in place.  I’m personally not a fan of this type of installation method, as I’ve had a few heavy heatsinks fall off that followed this methodology.  If your motherboard lays flat (as in a home theater or desktop case) then you probably shouldn’t worry.

Regardless, the heatsink feels very secure, and doesn’t appear to be going anywhere.  We tested the heatsink with an Intel Core 2 Duo processor under idle and load.  Temperatures were measured using the processor’s own thermal sensor (motherboard sensors are usually very inaccurate).
