5 out of 5 eggsRosewill RCX-Z90-AL

Pros: This works nicely for what it was designed for.

Cons: n

Other Thoughts: This is rated at 86 watts for cooling in the specs. I put it on a 65 watt processor. Then set the fan speed to the lowest setting in the bios. I have been using the machine that it is in for normal household surfing and social media. The speed has yet to leave the idle speed. This makes it one of the quietest coolers that I have had.

5 out of 5 eggsAmazingly quient

Pros: Amazingly quiet. Far more than I expected, especially for the money. Purchase one at 10 bucks. Then two more at 4 bucks each as spares.

Cons: Nothing

Other Thoughts: All things being relative, it works perfectly well on a system used in an office environment with low load applications. If you're looking for high performance you should do your research first.

5 out of 5 eggsGreat little cooler at a great price

Pros: I was building a linux-based PC with leftover parts from a deceased high-end Dell XPS. I needed a new CPU cooler, since the stock XPS CPU cooler is massive and didn't fit my new case. This cooler fit the profile I needed completely: low price, great value and great cooling.
- GREAT value for the price you pay.
- Actually much better looking in person than in in the Newegg pictures; well built fan/cooler.
- Already comes with well-applied thermal paste.
- Nice sleeved power cable.
- Altough other reviewers have stated otherwise, on my build (which only has one chasssis fan by the way) this fan is MORE than enough to cool my Core 2 Duo E6700; temperature a steady 38C-40C at idle load.

Cons: Only one major con: the plastic "pins" that serve to screw down the cooler on the Motherboard. If you're reading this, chances are you know all about these poorly-conceived plastic pins that were used with Intel coolers of this generation, and this cooler is no exception. The pins are flimsly and only by pure luck it seems I managed to adequately install the cooler without breakin a pin.
If I where to look hard for another con, yes, it is a little louder than other fans, but not enough to disturb me in my opinion.

Other Thoughts: All in all, taking into account the plastic screw pins, this is still a great buy at this price, and does its job magnificently.
Recommended for anyone looking for a great CPU cooler for older-generation CPU's.
I would rate it 4.5 out of 5 eggs, docking half an egg for the plastic pins, but since Newegg doesn't accept half-egg ratings, I'll give it a perfect five.

3 out of 5 eggsNot for AG8

Pros: inexpensive

Cons: Didn't work for me as a replacement for intel stock fan on older AG8 motherboard. I tried 3 different thermal paste but it kept overheating my P4 550. Looks identical to the stock heat sink (except it's not copper core).

Other Thoughts: I never had problems before w a heatsink. I triple checked installation , push down & turn to lock ? It all felt secure. I got disgusted and thew out the older motherboard.

4 out of 5 eggsQuiet and Reliable

Pros: The fan is quiet, reliable and reduced the temperature of the CPU by 10 degrees C. It was installed on an old CPU (8 years old) - it works.

Cons: Lack of instructions - a simple set of instructions would have made the installation easier....with any technical knowledge it was fairly easy to isntall

5 out of 5 eggsWinner!

Pros: I was able to get this fan in and running. Took me several attempts, but it's in and doing the job. And for that I'm grateful because my PC was not able to run for very long with the new CPU I purchased for it. It kept shutting down due to thernal failure. I needed a better cooler and this one worked.

Cons: As are all clip/push down fans, this one had my thumbs burning before it was on properly. Not blaming's simply the nature of the beast.

Other Thoughts: I'm glad I purchased this cooler.

4 out of 5 eggsA decent cooler

Pros: Cools CPU
Doesn't break the bank

Cons: A little difficult to install. Directions not very concise. One of the attaching pins bent during installation and it took forever to pinch it back into place as it is made of plastic. -1 Egg for cheapness of parts and lack of quality instructions.

Other Thoughts: You get what you pay for, folks. I would not recommend this for any CPU other than LGA775. You're probably better off with stock HSF for 1150/1155 even though that thing is terrible, too. There are much better alternatives out there for a few more dollars.

5 out of 5 eggscheap, quiet, works as expected

Pros: inexpensive, very quiet, does a good job of cooling, has 4 pin connector for smart cooling, well worth the $10

Cons: usual plastic push pin thingies in each corner that expand and hold heatsink to mobo. They seem to work fine and don't come loose but they seem kinda wimpy to me.

Other Thoughts: Had to replace a growling fan on an old eMachines LGA775 ECS motherboard. This one fit right in and cooled as well as te OEM heatsink/fan. It has the correct 4 pin fan connector for the smart fan speed control.
