5 out of 5 eggsAwesome!

Pros: Excellent cooler. The only thing quieter would be a water system. I can't believe how quiet this thing is. I didn't realize how loud my other fans are until I got this. Oh yeah, it keeps the temps way down.

Cons: None at all.

Other Thoughts: Dump that factory fan and get one of these. You won't be sorry.

5 out of 5 eggsIce Cold!!!

Pros: WOW! This fan lives up to it's name! Put this on an E4500 with a DG965OT board and I'm running 29C idle, and 36C under 100% load. Nice! It's compact too which makes installing a snap! didn't use any premium paste, just what came with the fan.

Cons: Nothing! works perfect!

Other Thoughts: Why didn't I use this fan before? LOL

5 out of 5 eggsgreat fan

Pros: temps dropped, very quiet, looks nice with a see-through side panel

Cons: pins are a pain to install on the motherboard, spacing issues with PSU

Other Thoughts: installed 2 of them, and they work perfect. removed pre-applied thermal pad and applied Artic5. I will continue to buy these fans for any setup I use.

5 out of 5 eggswow!!!! it's great!!!

Pros: easy install.
i bought this cooler because i've been putting together a new system.
i had a dell, that i've now destroyed to get this up and running. i bought a p4 3.4gh OEM processor. OEM=no cooler for cheaper, that way i didn't have to worry about what i was going to do with the heat sink.
and the fan is no louder than my new case is.
my case is running 6 80mm fans, and my cpu is currently running at 31c.

Cons: i can't really come up with any at all,
easy to install (pro)
not too loud (pro)
works well (not a con)

4 out of 5 eggsIt Works

Pros: I've had this fan installed in my computer for about a week and so far so good. It cools my CPU about the same as the stock one I had, maybe a little cooler. Definitely quieter than my last one.

Cons: I wish I could control hot fast the fan blows.

Other Thoughts: Pentium D 2.8
Average temp 40-45 C

5 out of 5 eggsBuy this

Pros: Not huge like some coolers, fits in my micro ATX cast with no issues. Still leaves room for the air duct. My pentium D idels at 18-20c and under load it never broke 27c. Quiet too.

Cons: None, like I said buy this

Other Thoughts: I am no gamer so I couldnt tell you about all that. All i know is that I wiped off the grey stuff that came with it and put on some artic silver 5. I spent 3 hours downloading all my songs onto this computer and it never broke 27c

5 out of 5 eggsUpdate to my 7/19/2007 review

Pros: I have had this cooler for just over 2 months now and it is still goin strong and doing better than ever. this thing is on my Pentium D (currently at ~3Ghz) and my proc is idling while i write this at 26C. this is in my apevia x-qpack 2 case (sff cube) i applied with arctic s*lver and bumped the fan speed to 1500rpms and i still cant hear it over any of my other case fans. i have never seen my temps go above 42C even at load (though i have never done a burn-in test it still seems amazing to me)

Cons: NONE!!!

Other Thoughts: dont let it's diminutive dimensions fool you this thing hangs w/ the big dogs. i just helped a friend build a pc w/ an amd set at ~2.5Ghz and he has a 140mm tall heatsink/fan (almost double the size of this one and w/ twice as many heat pipes) and his idle temps are at 34C. thinkin about trying this thing on a core 2 quad Q6600 and seeing how it will do..

5 out of 5 eggsDoesn't get any better!

Pros: Copper core,3 heat pipes,easy install with thermal solution already applied.Fits cold air funnel perfect and motherboard controls speed,usually around 500-RPM!SILENT.Fan half size of thermaltake on my AMD but keeps this intel proc COOL with a total lack of sound.

Cons: Wish I had bought coolermaster coolers earlier!

Other Thoughts: For a intel 775 proc. which tends to run hot this is the only way to go.

5 out of 5 eggsGreat CPU/Heatsink

Pros: Great Price, just as specs say low profile which is great for my Intel motherboard and easy installation! Runs quiet, quieter than my stock CPU fan and doesn't speed up that much, creating more noise.

Cons: No thermal solution came with it which is ok since I have some but even my stock CPU fan/Heatsink came with thermal solution.
