4 out of 5 eggsGreat cooling loads and static idles

Pros: First build and it's nice effeciency on cooling.

a AMD 6300 FX stays at 37-39*C idle depending on temp of house

and on high loads is 45-48 *C

I recommend this on first build for its price.

Cooling profecient and sturdy

Cons: it's difficult to assemble so make sure you pay attention to the directions. if it's installed wrong it will not touch the processor, and the processor will shut off on heat in 10 seconds or less with start up. Keep an eye on that and you shall stay solid!

5 out of 5 eggsgreat CPU cooler

Pros: This cooler reduced my CPU temps from 150 f to 90 f. I wish I had installed this unit from the beginning. It is a TIGHT FIT next to fully populated RAM modules with heat spreaders, but it did fit (just barely). The fans are quiet - set up in a push-pull arrangement. Decent, straight forward instructions are included which I strongly recommend reading first..The fit and workmanship on these products is superior - a Phillips screwdriver is included. Overall, a quality product.

Cons: Other than the tight fit next to the RAM, none.

Other Thoughts: CPU coolers are one of the trickiest parts of building or upgrading a system. Installing it, like any CPU cooler with the main board already in the case, takes some work AND PATIENCE. Your case has to have a cut out in back to expose the back side of the main board which most modern ATX cases have. I used some small pieces of tape to temporarily hold the back plate in place while assembling the two piece mounting brackets from the front - no big deal. I cleaned off the old compound with rubbing alcohol and 'Q' tips. If you approach the project systematically, don't rush, and follow the procedures step by step, it will work out well. With this cooler, CPU temps and fan noise will be dramatically reduced over stock coolers.

5 out of 5 eggs

Pros: Very high quality. Easy to install. Includes thermal compound. Quiet. Significantly lowers temperatures compared to stock cooler.

Cons: Wish it came with PWM fans.

Other Thoughts: Installed this in an InWin 901 case with Core i7-4790K processor. Idle temperature dropped by 10C and load temperature dropped by 20C.

This is not a difficult install, contrary to what some people are saying. My case is relatively tight and I had no issues with installation at all.

5 out of 5 eggs  high quality and silent

Pros: Well engineered piece of equipment. Works like a charm and is 100% silent. It went together well and arrived with all of the appurtenances needed for any type of install. Directions are so detailed even a novice can't go wrong.

Cons: A bit tight over some capacitors on my board, but so far so good.

5 out of 5 eggsSuper Quiet and Cool!

Pros: Stock fan temperatures were 42 Celsius at idle and over 65 under load. This fan keeps my cpu at 33/ 45 and even with the case open i cant even hear the fans from a couple of feet away. Several times quieter than any other fan on the computer!

Cons: I removed a stick of memory to get it to fit but there is room for it once you have it in place(mid atx). measure for clearance.

Other Thoughts: Would recommend to anyone!

5 out of 5 eggsbreathing new life in old rig

Pros: 1. Size: Having read some other reviews, I specifically chose this one over Noctua's 120mm and 140mm heatsinks, based on potential clearance issues with both ram and the case itself. turns out that the 92mm was a perfect fit on the old Gigabyte ex58-ud3r board. There was room for both fans.

2. Temps: 20C less than stock cooler. I forgot to put an aftermarket HS in the cart during the initial build and was just lazy about upgrading from the stock cooler, the amount of cooling will give me enough overhead to finally be able to do some decent overclocking.

3. Straight forward instructions with pictures. My rig is an intel platform, and the packaging was very straight forward on which set of instructions to follow, and with intel, which specific instructions for the appropriate socket type.

Cons: Installation does take some work. Ideally, installation should take place on a fresh build, before the mobo is put into the case (In my scenario, it took some time to get the mobo out of the case for installation of the backplate). Once the backplate is secured, the only other challenge is the mounting brackets for the fans; those do take some fiddling with.

Other Thoughts: 3 day shipping from Newegg arrived a day early. Very pleasant surprise.

My rig is 6 years old at this point, a 1st gen i7 on the 1366 socket. While it was bothersome to take apart most of my rig to but in this new cooler, it gave me the opportunity to reorganize my case airflow quite a bit to better synergize with the Noctua cooler.

I am pleased so far with the Noctua cooler.

5 out of 5 eggsWoah

Pros: Quiet
Keeps the CPU cool even while overclocking
Very good design
Great packaging and parts
Instructions were clear and informative

Cons: Honestly the only thing I don't like and it's a little gripe is the colour of the fans, but that's just me.

Other Thoughts: First time buying from Noctua and I gotta say they've made a fan of me. Great product and a lot of steps were taken to ensure your cooler would be quiet and some of the things they've done I would of never thought of myself. If you're looking for a quiet but excellent air cooler this one takes the cake. (No it is not a lie, this time.)

5 out of 5 eggsGreat cooler!

Pros: This cooler works great! I'm using it in a norco 450b case cooling an i7-860 and haven't had any issues. With a single 92mm fan I'm seeing around 45 degree coretemps under 100% load for 30+ minutes!

Cons: None
