ARCTIC Freezer 11 LP - 100 Watts Intel CPU Cooler for Slim PC Cases, Intel LGA 1700, ultra quiet 100 mm PWM fan, pre-applied MX-4 Thermal Compound

I replaced a stock Acer cooler. The Acer one did a fair job, and it had a cone that pulled in air from side vent. Therefor it had cooler air rather than recycling the hot air in the case. Unfortunately at every frequency of its variable rotational speed, it made a different pitched whinge and it was quite loud.Anyway this Arctic Cooling unit has taken a few of degrees off the (gaming) load temps. Idle temps are the same. The real beauty is that it makes no noise. I mean if I get down on the floor, and have the case side off I can hear the airflow. That's acoustic dynamics though, and is exactly what I would expect. It must have good bearings, which I think is why it's rotational operation is quiet/silent. That is what I read about and learnt when looking up reviews on it.It's very simple to install for Intel. (I viewed a Youtube fitting video, and genuinely it could not be easier.) It is quite large but I think it's the smallest of its type. I like that it pulls air in the directions it does, and exhausts towards the PC case rear vent holes. It is also pulling cool air across the RAM modules, so that can't be a bad thing.Professional reviews all sumarised it 'a good cooler, but a little more money gets you lots more'. Anyway I decided on this because of size, and low cost. I spent ages looking at the dimensions and measuring inside the PC. I couldn't fit a wider system. More expensive ones use wider fans and heatsinks.To recap. Perfect for the job with my CPU.For socket support, internet search 'Arctic Cooling Freezer 7 Pro Rev.2 CPU Cooler', and visit the Arctic Cooling web page for this item. In the default first tab 'description', scroll to the bottom of the page and view which sockets it supports. You'll see what you need to know under, 'Intel AMD - Wide Compatibility'.N.B. I have ordered a 92mm Arctic Cooling case fan, because of my success with this.

damn good fan. keeps my quad core phenom iix4 975 idle between 30 and 37 degrees. stress tested on low power consumption for thirty minutes with prime 95: all cores 100% full load 30-37 degrees. have not yet tested on full power consumption but it keeps it low between 40 and 50 degrees when using multiple applications same time lol.one thing bothers me as i am a total noob at cpu upgrading etc etc. the PWM controls, i cannot find because even though it keeps temps low at maximum 1700RPM... i still want some 2500RPM coz damn this lil guy is quiet. i got HDD fan that makes more noise than whole computer!pros:quiet, keeps it cool, fits into my ANKERMANN atx midi case. (dont ask what the hell it is, plz just think regular 16 cm wide case ok)cons:damn fat-finger pain to fit into amd motherboard. mine is am3+ M5A78L-M-LX. it got mx-2 already applied - not bad but i got mx-4 arctic paste and dropped temps by -5degrees.conclusions and after thoughts:i know i can get lower temps. just need to know how to turn off PWM controls. lol. that's gonna be fun. that's my budget done for that. might buy the big 13 freezer pro next as the BULLDOZERS come crushing through over all cpus! i have to keep it secret from my girlfriend. dont want Noctua as my case wont fit them in. those super beast fans but do not come close to the invincible NOFAN cpu fans. absolutely ice cool and silent.... i will update this as i do more tests but i am loving the lil pain in the fingers b......d!******UPDATE!!!!!Wow. figured the reason why it never shot above 1750 rpm. asus q-fan. doh! noob! disabled and now fan runs full throttle and less noisy than stock fan at full power. gonna upgrade to fx 6 core. i am not oc. no way. just want fast efficient cooled system****UPDATE!!! 2012I bought the amd fx 6100 6 core processor in august this year.installed Hardware monitor and CPU-Z CORE TEMPcpu temp ranges from 29degrees c to 35 degrees Celsius idle and core temp from 10 degrees to 18 degrees at idlemax setting idle at 35 to 40 degrees and core temp from 16 to 25 degrees. I am a casual gamer with more interest in editing photos and videos. on that note; photo and video editing on basic cyber link software is fast and I rarely go over 45 degrees cpu temp. core temp varies from 20 to 35 degrees.played sniper v2 and hard reset at max setting on hd 6670 and got 40 - 45 degrees Celsius and 18 to 30 degrees core temps.great cpu fan. and keeps my system running cool. bit noisy at full throttle maxing 2270 rpm but keeps things cool. at low cpu function it is at 995 rpm and barely audible. my pwm arctic cases fans on pwm connector are noisier.
