Installing this product was not easy. If you have an AMD based system, take EXTREME CARE when removing your existing OEM cooler from Phenom II CPU's

Mine had glued itself to the OEM cooler and removing the cooler pulled the CPU from its socket, bending pins on the processor. After over an hour of delicate work, I managed to straighten the pins and replace the CPU into its slot. Very frightening.

After the above crisis, fitting the Arctic cooler is fiddly but not to difficult.

In use it is almost silent and a revelation compared to the OEM cooler.

Very pleased with this product thus far.

Just PLEASE be so very very careful if you are AMD based.

Simply amazing, for the price.

Idle 25 Degrees, Prime2004 Load 36 Degrees.

(Just threw together a budget PC. This is attached to a PHenom II 560 (dual core),

overclocked by an additional 400 Mhz, no change in voltages.)

Case itself has good airflow and a side fan, which maybe improving performance, but even with that taken into account. 36 Degrees Load is very very impressive.

This CPU Cooler is an amazing purchase for the tiny sum of money that it costs, i have a Core i5 760 running stable at 4GHz which is a 50% overclock and i never exceed 70c and i never have thought to myself that the fan was excessively loud which is always a bonus. It may seem high but for such a cheaper cooler and a massive overclock it really is a brilliant product.

I was unsure at first at what CPU fan to purchase, after coming across this I have no regrets. The fan is very efficient at cooling the CPU, its never gone above 40 degrees when heavily loaded with games etc. It is also very quiet. Well recommended to all. Thanks.

First, installation: The fan was relatively easy to install, the only difficulty being that it's hard to get the screws to connect to the attaching point on the motherboard. The pre-applied thermal compound is perfectly good, and saves money and messing about.

Second, performance: The fan performs admirably at around 1500rpm, keeping my CPU at around 31C when browsing and listening to music, and the temp doesn't go above 39C when gaming. At this RPM, it's inaudible above my case fan.

Cons: The cons of this fan are that it does obstruct the first RAM slot on my motherboard, so I can't have a full complement of memory, but for the average user, 2 slots should be enough. Also, in an AMD system, the fan either blows up or down the case, which isn't great for cooling.
The main problem however, is that it sometimes causes a problem when booting up, and you need to press F1. This can be solved by disabling Qfan in the BIOS, but then the fan runs at a stead 2000 RPM, and can be heard a lot.

Good cooler but too large for the Asus M5A99X EVO AM3+ fouls the first memory slot due to the heatsink orientation. For some reason its been designed to blow down the board instead of the usual across the board and out the rear vents...

Bought Artic Cooling Freezer 7 as so many recommendations online. Overall I am very pleased to say that it lives up to all that I read. Phenom II 955CPU core temps idle around 26c and under load no higher than 39C, not overclocked. It is also very quiet.

However, this is the first time I have installed a CPU fan and it was a little tricky to fit. The fan unclips to make installing easier and all the parts were fine, but on my MSI 870A-G54 board it was almost too big to fit without touching the RAM, only a couple of mm clearance.

The metal clips that attach the cooler to an AMD CPU bracket work fine, but are not easy to get the screw to connect the two parts. Once that is done though it is very secure and works very well.

This fan/heatsink is fairly large. It effectively ruled out one dimm slot on my MoBo (ASUS M5A97 AMD) which I had kind of expected anyway.

Fan and motherboard didn't play well together, with the RPM of the fan being detected as 0 or 950,000 periodically. MoBo has checked out okay, so will be returning the fan. This caused stability issues, in Win XP. Didn't try in Win 7, but didn't fancy taking the risk.

A bit fiddly to fit (access to the 2 screws, and reattaching the fan), but well worth £15.

My motherboard (Asus P8Z68-V) will not power the fan on the heatsink. The mobo requires F1 to be pressed at each boot. I'm currently having to use it passively, which it actually does surprisingly well, whilst having CPU fan monitoring disabled.

Be aware & check your motherboard will support the power this unit needs. We found on 2 ASUS motherboards this blew the first & the second new one makes the user press f1 after halting with a warning message. If you have a quirky fitting to power this from the PSU you will need a basic one connected to the CPU fan socket on the motherboard so that's a waste of money!!
