Summary: You may want to spread the thermal grease that is included with this heatsink, spread it out real thin or just buy some Masscool Fanner 420. I will conduct some more tests but I think I am correct.
Pros: I've noticed on high load with the stock aluminum heatsink i own (6000RPM,60MM fan) produced the same results as this fan. Quiet High CFM High RPM 92MM
Cons: Installed many heatsinks in my day but this by far was the hardest... Used a flathead screwdriver like every other time and the heatsink's clamp flew right off. Thank heavens, I had a pair of needle nose pliers.
Summary: The first gaming PC i ever built has an Athlon 3000+ cpu, and a sentimental attachment makes it hard to trash the old machine. So i ordered this Rosewill cooler and did the usual fiddly lever-the-retaining-clips-wth-a-screwdriver trick to install it (after cleaning off the old thermal paste of course). The result is cooler running, and the old PC lives on to serve as an occasional backup machine.
Pros: Cools better than the old stock cooler on an AMD Athlon 64 3000+ cpu. Also it's slightly quieter than the stock cooler.
Summary: if you are careful, removing the fan shouldn't be a problem. The people that are complaining must have not have worked on to many socket a systems. All socket a fans are a pain to get on. All socket a fans that attach to the heatsink do it in this manner. This is nothing new. Be careful and you will be fine. Unless your screws are stripped out from the factory, in which case, yeah, RMA it.
Pros: It's big and quiet and keeps even Bartons cool. My 2800+ socket A Barton ran at 50 idle with the stock cooler and this makes it run around 39 idle (also using ArcticSilver5).
Cons: You really need to remove the fan to get it on.
Summary: Overall, this is a decent cooler, although it didn't decrease my temps as much as I had hoped. With the old cooler, I saw 59c under load; now load temps hover around 52c, and that's with the addition of an 80mm exhaust fan and removal of BIOS fan control. Ultimately, though, reliability is gong to be more important than performance. I bought this cooler for use with a system which sees 100% CPU utilization 24/7 with the SETI@home client.
Pros: Bought this to replace the stock cooler on my Sempron 3000+. Socket A is getting pretty old, so I'm impressed that Newegg still stocks this part. This cooler lowered my temps a few degrees and is fairly quiet, even at full blast (large fan + low RPM helps). Contrary to other reviews, my Compaq-branded Asus motherboard seems to be able to read the RPMs and adjust the voltage dynamically, though I've disabled this function for maximum cooling performance.
Cons: Installation was a little tricky. I recommend removing the fan from the heatsink, removing the pre-applied thermal paste, and doing a few dry runs before applying Arctic Silver and installing it "for real." In my case, the metal clamp was way over-bent and had to be adjusted with pliers before it would fit. When re-attaching the fan, be careful not to over-tighten the screws. This seems to be a weak point in the cooler's design, as the fan screws directly into the alu...
Summary: Still over all, the product works great, and it brought life back to an old AMD Athlon XP 2800 machine. One egg removed mainly do to slow Fedex. I don't trust Fedex with shipping anything.
Pros: Barely, but still fits an Abit KV7 motherboard. Quiet. Fan matches the motherboards color. Glows an awesome looking purple with my blue LED Case fans.
Cons: Had to remove the fan for install. (no egg removed) Fan RPMs not seen by bios, but it's an ancient board anyway. Speedfan reads the RPMs just fine (no egg removed) The box could have been better packaged. Fedex took its sweet time delivering even though it was the Eggsaver shipping option, UPS could have had it here faster.
Summary: The fan housing is a worthless piece of structurally insufficient, and airflow-losing garbage. Take a close look at the picture and you'll see slots running all along the outside of the housing. Those slots allow air to escape from the side, instead of being forced down onto the heatsink. I fixed it with some tape. Not even docking an egg for it.
Pros: Nice HSF for an aging socket (A / 462). Copper base for better heat absorption. Quiet (until now anyway). AMD Athlon XP 3200+ (Barton Core) @ stock settings with Artic Silver Ceramique 2. Idle temp @ ~44C Load temp @ ~57C
Cons: Poor housing design. Hasn't lasted as long as the original Antec fans that came with my case (10+ yrs. and counting).
