Thermalright Ultra-120 eXtreme Rev C. CPU Heatsink is an upgrade on the highly accoladed Ultra-120. Featuring more heatpipes, a larger fin area and better heat dissipation, the eXtreme is compatible with Intel's Socket 1366 / 775 and AMD AM2 right out of the box - no accessories needed.

Note: For those on a budget. This unit does come with 1 set of 120mm Wire Clips to hold 1 fan attached to the heatsink.

**Note: LGA 1156 and Xeons require the optional Bolt-thru-kits in options below!!

Fan holder and 120mm Fan are sold separately! (Stock 120mm x 25mm fan clips are provided)

Features

• Uses high quality aluminum fins for best balance of heat absorption and conduction.
• Utilizes six high quality 6mm heatpipes, strategically positioned to pick up the heat from the CPU.
• Proprietary bent winglet design to minimize airflow resistance.
• Heat pipes soldered to base (nickel plated) and fins for optimum heat transfer.
• Stack of 52 pieces of aluminum fins, the most over any other heatsinks in the market. Can be covered entirely by a 120mm fan to absorb all in-coming air flow.
• Vast compatibility list for multiple multi-core CPUs and platforms.

This heatsink exceeded my expectations. My Q9550 is at 3.65GHz prime95 stable for 24 hours with max temps under full load at 55C. My previous heatsink was a Zalman 9500 and my temps would reach 68C and was only able to overclock to 3.2GHz. I highly recommend the Ultra 120 extreme Rev C. I''m using a 63CFM fan so it''s very quiet as well.

The baseplate on mine was VERY uneven. Apparently quality control at Thermalright does not check for flatness. Unless you consider an evening of lapping a new heatsink a good time, I would skip this one. Otherwise, after lapping, it works great; temps way down now!

The bottom of this heatsink has ridges large enough that your fingernail makes a zipping noise if you run it across. Having read another review about that possibility, I got the lapping kit here (will write review on that after this). Anyhow, delivers as promised. My CPU is super cool! My install is currently curing, but temps far below oversized stock QX9650 cooler.

This Heatsink drops my idle temp from 24c to 17c! load temp doesnt hit above 25c! Using a E8400 @3.6ghz 1.225v

Pros - Retention is amazing...spring mounted screws - Cooling is amazing...keeps my Processor at ambient at idle, below 50 at load (Q6600 at 3.45Ghz and 1.6v) - 120mm fan of your choice can be attached - Fan retention is a lot sturdier than it looks - Effective fan vibration dampening - Less expensive than the water cooling kits that it absolutely OWNS - Beautiful construction - 6 HEAT PIPES! - It''s the Ultra 120 A on steroids Cons - Huge - Sometimes too powerful to handle...hehehe
