Rosewill RCX-Z5 92mm Two Ball Bearing / FDBB CPU Cooler

Pros: -Fast and easy installation
-Fan and Thermal paste included
-Great cooling
-Relatively light
-Very quiet even at full speed
-Excellent value for money

I just installed it a couple of hours ago and achieved an instant 10-14C drop on idle, and a whopping 30C drop on 100% load.

I got this cooler when NewEgg had the shellshocker deal going on. Saw several positive reviews and a few negative ones, but thought I'd go for it because of the low price. Am I glad I did!

It is also relatively light, I remember the Zalman on my old PC that weighed about 4 pounds and was worried if this would cause my motherboard to bend. But the Z5 felt much lighter and feels more secure on the board than my intel stock cooler.

It's very quiet - I could hear my intel cooler kick up and it sounded like it's going to take off, and this was on an Antec case with 6 other fans running. Now I can barely hear the CPU fan at 100% over my case fans.

Overall, I'm very happy with this cooler.

Cons: * Needs precision screwdriver to mount CPU-adapter. I didn't have my tiny watch-screwdriver set handy, so wasn't pleased about the real tiny screws that they provided to secure the CPU adapter to the cooler. Had to improvise using a kitchen tool but this is not enough to take away an egg. It would be nice if they provided standard sized computer screws (similar to HDD ones) so a regular screwdriver can do the job.

* The latches that need to be rotated to remove the cooler is BELOW the fins, so a screwdriver cannot reach it easily and access the slot on the locking latch from straight above. It's not that hard to turn them using bare hands though, so this is not a big deal.

Overall Review: I have a Q6600 running at stock speeds and my intel stock cooler was terrible. I used to get 42-45C on idle and once the temperature of the hottest core went up to 72C while I was doing some video encoding. That's when I decided to get a new cooler.

I was leaning towards Tuniq, ThermalTake, Coolermaster etc which are relatively expensive and have been putting it off because of the higher prices and due to the fact that I'd have to get a separate fan for some of those (another 15 bucks or so). When I saw the Rosewill for less than half the price of the other ones, and because it included the thermal paste AND a fan, I couldn't pass it up.

Now I get 28-31C on idle and 42C on my hottest core and 39C on the coolest one at 100% load. The reason for the low differential between high/low temps is that I kept my fan at 25% on idle and when the temps go up, it kicks up to 100% (mobo bios). I'm going to bump up the idle RPM and see how much more it can cool when the CPU is idle.

Pros: It looks great, and it really keeps the processor cool.
It kept my 2.2GHz E4500 (65 nm), overclocked to 2.9 ghz around 70C when folding.

Cons: It broke after 5 minutes. After a successful installation, I put the computer upright, started it, and began folding. 5 minutes into the folding, I hear a pop, so I look inside. The cooler is sagging on one side, because a clip popped out. After removing it to see what the problem was, I find that the little mounting pins on the one corner are completely gone.

The poor build quality on the mounting pins (intel) caused it to break off.

Overall Review: If you're on an AMD board, go for it, the AMD mount looks solid enough. It keeps the processor nice and cool, and it has LEDs.
If you're on an Intel board, STAY AWAY.
