be quiet! Pure Rock LP: 45 millimeter high cooler for 100 watt TDP

be quiet! competes in the segment of super-flat processor coolers. The Pure Rock LP is only 45 millimeters high, but the manufacturer promises it should offer enough power for “an ordinary mid-range gaming system”.

When designing flat coolers also has be quiet! Little choice: The heat sink, which is only 30 millimeters high, is cuboid like its competitors and makes full use of the free space around the processor base. Together with three heatpipes, this should be enough for a TDP of 100 watts.

The fan used plays a role here. This is where be quiet! back to a 92 mm model with a 15 mm thick frame that has a maximum speed of 2,500 rpm. The fan is bolted on the Pure Rock LP, so using a larger model will likely require longer bolts.

Since the cooler can only handle a moderate TDP, it can only be used on mid-range platforms. It is mounted on AM4 and AM5 mainboards as well as the LGA 1700, 1200 and 115X. The Pure Rock LP is screwed directly from the back of the main circuit board.

Cooler in comparison

The newcomer will be available in stores from December 13th at a recommended price of around 50 euros. In terms of price, it is more based on Noctua and Co and sees itself as a larger, more powerful version of the NH-L9i, which only has two heat pipes and flatter fins.

However, coolers with more heat pipes are also available for less money. The Jonsbo HP-400, for example, is said to be able to dissipate a little more waste heat, but only costs around 29 euros and is complemented by the completely black HX4170D. The most likely direct competitor is the 40 euro expensive, similarly sized Silverstone Argon AR11, which, however, leaves the heat pipes and fins in their natural state. With the Hydrogon H90, however, Silverstone has another caliber ready for 50 euros, which is 48 millimeters high and uses six heat pipes.
