Thermalright Ultra 120 eXtreme
The Ultra eXtreme is sent in a horrendously boring box, which doesn’t list the specifications and doesn’t give you any marketing spiel. While the box may be boring, it does say something about Thermalright’s confidence in this product. Obviously, you’re unlikely to find this on a shop’s shelf and if you want one, you’ll hunt one down online.
In the box you’ll get a whole host of little bits and pieces, including an English language manual, a French manual, the cooler itself, an AMD mounting bracket, an Intel mounting bracket, two fan clips, two anti-vibration strips, a tube of heatpaste, an Intel backing plate and spring screws for both Intel and AMD.
The Ultra eXtreme builds on the Ultra which only had 4 U-shaped heatpipes . This beast has a total of 6 U’s which should send heat faster to the cooler tip of the heatsink which is often left unused as heat never gets that far.
The eXtreme has an interesting fin shape, the tips of the fins are bent either up or down. This should create more air turbulence and hence more time for the air passing over the heatsink to pick up heat from the fins. While air turbulence does mean more noise, I doubt that this tiny bend in the edge of the fin will mean a massive increase in dBA.
The fins themselves are quite thin, but not fragile (i.e. easily bent). Thicker fins are normally present on passively cooled heatsinks, while thinner fins are normally associated with active cooling solutions. This heatsink appears to be the mid way point, allowing for passive usage if you so wish.
The bottom of the heatsink has the contact point between the interface pad and the heatpipes. Here you are at the apex of the size heatpipes, which then bend upwards through the fins transferring heat as they go. This means that heat is sent quickly up to the entire heatsink rather than waiting for the heat to slowly travel up through solid metal. Hopefully this should mean that the whole heatsink is the same temperature, rather than the lower section being considerably hotter than the top of the ‘sink.
The bottom of the heatsink doesn’t come with a ridiculously patronising ‘remove before installation’ sticker on the interface pad. Instead it’s left bare and it’s nice and smooth. There are still some visible machine marks however, but they shouldn’t affect temperatures drastically.
On the top of the eXtreme you can see where the heatpipes terminate and also an etched Thermalright logo. The whole heatsink is nicely finished and has an air of quality about it.
