Thermalright Ultra 120 eXtreme Rev.C Review

» Discuss this article (1)


When it comes down to it, the Thermalright Ultra 120 eXtreme Revision C heat sink does an effective job cooling down the processor. With the Core i7 920, just about anything better than the stock Intel cooling can keep the CPU under 30°C in an idle state. Where the TRUE earns its keep is when you throw a load on it. Each of the three Thermalright coolers in this test performed within 1 °C of each other. That shows the consistency of the product and shows that the design features on the Revision C really do the job with less surface area to cool the processor. The four fewer fins opens up the spacing so that you do not need to use a high RPM/CFM fan to get the cooling performance you need.

The included TR-FDB-1600 fan runs at 1600 RPM and pushes almost 64 CFM of airflow to get rid of the thermal energy from the CPU. It does this with a relatively quiet 28 db/A so you get both cooling performance and a low noise solution. The increase in fin spacing allows this cooler to be optimized for lower speed fans, a plus for the noise free crowd. Thermalright offers fans in its TR-FDB line up from 800 RPM to 2000 RPM. The Revision B mounting hardware included with this heat sink is a bolt through design that is a bit different than the earlier bolt through design. The best way to describe this mounting solution is if you have seen the SecuFirm2 mounting kit from Noctua. Instead of having an X brace with four spring loaded screws to get into place, you have a backplate that is held in place with the help of two mounting brackets that run parallel to the 1366 socket. There is a straight brace that comes across the heat sink base and is secured to the two brackets with only two spring loaded screws. This makes the process a little easier since you can mount the brackets, install the motherboard, then mount the TRUE. The nickel finish used on the TRUE looks flawless everywhere except where the bends are in the heatpipes. At this point the finish looks like it is ready to peel off like a bad chrome job and is really not the type of quality I am used to seeing with Thermalright's products. It's one small glitch and may be just a defect on my sample, but it's visible when looking at the heat sink. However, once you have it mounted in the case, it's impossible to see.

Current pricing on this package comes in at right about $65, putting in the higher end price range for a performance heat sink, but still much less than the premium the NH-D14 form Noctua goes for. If you want this heat sink sans fan and bracket you can get it for roughly $4 less, but then you can add the fan of your choice. This of course brings up the price, making the four dollar premium for the inclusion of the TR-FDB-1600 fan a bargain. The TRUE revision C offers great performance for a decent price with the stunning good looks that a nickel plated heatsink brings to the table. If your price point is right in the $60 range, you can't go wrong with the TRUE.
