ThermalTake V1-Ultra CPU Heatsink


A closer look

The package comes with the heatsink itself, an installation manual, and springs and clips for mounting.

The heatsink is one of the most interesting designs I’ve seen.  The heatsink is laid out like a sandwich; there are two major fin groups, and sandwiched in between them is a vertial-standing fan.  The fins are attached to the heatsink’s base vis four heatpipes, and the fan is mounted with a vertival-standing lever.

A rheostat has been built-in to the 92mm fan, which allows the user to modify the fan’s speed, which of course affects the fans noise (and cooling performance).  The knob is attached to a long black cord.  This is a great feature, but once the heatsink is mounted then the user will have to open the case to change it, so changing-on-the-fly is not a real possibility.  It’s more of a set-it-and-forget it type arrangement.  Most people will set it to their liking and forget about it, but if you are a LAN gamer, then you’ll want the flexibility of cranking up the performance when the room gets too hot.

Each major fin group resembles the shape of a fold-up paper fan, and is made up of many pieces of shaved copper.  Each copper plate is folded and soldered at the bottom and center of each piece.  The fold helps to maintain the spacing, and the soldering ensures that heat transfer is consistent.

The two fin groups are held together by a copper bridge, which has ThermalTake’s “Tt” logo stamped into it.  All of this folding, jointing and riveting makes the entire heatsink feel very solid, even though it looks like it could be rather fragile and bendy.

The copper base has been lapped and polished to a near-mirror finish, which helps to increase the surface area actually in contact with the CPU.  Above the copper base is an aluminum block which serves as the contact point for all the mounting hardware.
