Rosewill offers "the best choice in value" with its range of CPU coolers that offer high end features and performance at low end prices. There's still some life left in that AMD Athlon XP chip - and plenty of heat too. Rosewill has a long-lasting, affordable cooling solution that will prevent damaging heat build up while operating quieter than the stock fan.

The RCX-Z100 features a 92 RPM fan which moves an impressive 44 CFM of cooling air. Even at 2200 RPM, the fan only generates 22.5 dBA of noise. It has an expected lifespan of over 45000 hours – equal to over five years of reliable service. Its pure aluminum heatsink has a large dimension copper base to efficiently draw heat away from the CPU.

A 3 point fixed clip lets you install the cooler onto motherboards with an AMD Athlon XP 3400+ CPU using the 462 pin Socket A mount.

  • newegg Exceptional Cooling Performance The extra-large copper base and high-density aluminum fins optimize heat dissipation. Plus a 92mm, 2200RPM ball bearing fan delivers an air flow of up to 44 CFM for exceptional cooling performance.
  • newegg Adjustable Fan Speed With a 3-pin connector, the Rosewill RCX-Z100 supports fan speed monitoring so you can fine tune the fan speeds for the optimum balance between cooling performance and noise level.

4 out of 5 eggsSilent but design flaws

Pros: I've noticed on high load with the stock aluminum heatsink i own (6000RPM,60MM fan) produced the same results as this fan.

High CFM
High RPM

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.

Other Thoughts: 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.

5 out of 5 eggsEffective cooling for Low Price

Pros: Cools better than the old stock cooler on an AMD Athlon 64 3000+ cpu.

Also it's slightly quieter than the stock cooler.

Cons: none at the price.

Other Thoughts: 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.

5 out of 5 eggsGood fan

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.

Other Thoughts: 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.

2 out of 5 eggs

Pros: Quiet, cools, pretty much works.

Cons: Low quality. I've had 2 of these. One came broken. The other came warped. The fan enclosure touches the blades. It bens back into shape but sometimes returns to the non-circular form.

4 out of 5 eggsDoes the job

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 aluminum fins of the heatsink. If you screw the fan down too tightly, the plastic housing will warp slightly, causing it to make contact with the fan blades and produce an alarming noise. Loosening the screws slightly solved this for me.

Other Thoughts: 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. Hopefully this fan will last the full 45000 hours it's rated for.

5 out of 5 eggsworks well

Pros: Works, cools the chip well, does what it's supposed to, value priced, with a little modification works on many other sockets as well.

Cons: Not as quiet as some other solutions out there

Other Thoughts: Value priced cooler for old AMD socket A chips, cools them well, not much else to say. You can't expect heatpipes or temps to stay at 30C with something this inexpensive, but it does the job.

4 out of 5 eggs

Pros: Barely, but still fits an Abit KV7 motherboard.
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.

Other Thoughts: 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.

1 out of 5 eggsFalse advertisement apparently part of their business model

Pros: Nice CPU cooler 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.
Difficult to install
Hasn't lasted as long as the original fans that came with my case (10+ yrs. and counting).
False advertisement as a business model. Claims 5 yr. (45000 hr.) fan life-expectancy. Mine is dying in under 3 yrs of use and they won't RMA because the 1yr. limited warranty expired. Don't make claims about a product if you're not prepared to uphold them.

Other Thoughts: 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. Not even docking an egg for it.

Structure (-1 egg)
The main problem is that the (minimal amount of) plastic they used to make the housing is SO structurally insufficient, that if you screw it down onto the heatsink too tight, it will warp out of shape and come into contact with the fan blades. You don't have to be a rocket scientist to know that's not a good thing. Since there's no real mounting solution on the heatsink (the screws just wedge in between a couple fins), there's not enough support to keep the fan from flexing. This tells me they tried to cut costs by sacrificing material.

Longevity (-1 egg)
As stated previously, my original case fans (80mm and 10+ yrs. old) outlasted this thing, and they're STILL going strong with no signs of quitting.

At times this CPU-fan sounds like it's about to break loose and sprawl through my case, killing everything inside. That is when it's not spinning down to UNREADABLE RPM levels. I've seen it run as high as ~2100 RPM. As I write this it's hovering between 1700 and 1800 RPM. Earlier, the fan was running SO slow I could clearly see the logo on the sticker spinning at the center. Not cool at all (no pun intended).

False advertisement (-all eggs) This would be a 0 egg review if I could do it. I hope you like losing my business and anyone else I can turn away from your products.
