Rosewill continues its commitment to being "the best choice in value" by producing CPU cooling products with high end performance without the high-end price. Part of Rosewill's "Z" series designed specifically for Intel processors, the RCX-Z300 performs comparable to higher-priced units but at a fraction of the price.

The 92mm red fan spins at speeds up to 2200 RPM allowing it to move nearly 42 CFM of cooling air. At top speed, it generates a noise level of just over 24 dBA. Its integrated PWM functionality offers great flexibility by allowing the system BIOS to monitor the fan's speed and performance. During periods of low thermal need, the computer will lower the fan's speed – and its noise level.

The heatsink portion of the RCX-Z300 consists of aluminum extrusion fins surrounding a copper base and core. These convection fins have a branching, "crotched" profile which practically doubles the amount of surface area available to diffuse the surplus heat. The RCX-Z300 will support Intel Socket LGA 775 processors including the Core 2 Extreme, -Quad, -Duo and Pentium D, -4 and Celeron D CPUs.

  • newegg Excellent Cooling Performance The Rosewill RCX-Z300 features a pure copper base and high-density aluminum fins, plus a powerful 92mm cooling fan to deliver superior cooling performance.
  • newegg PWM Function The PWM function automatically adjusts fan speeds according to the CPU temperature for efficient cooling and minimized fan noise.

5 out of 5 eggsWorks great; Looks cool

Pros: Looks really cool.
Keeps the CPU cool.
Farly quiet.

Cons: You need a motherboard that allows for a medium-wide heat sink.

Other Thoughts: I put it on my Core 2 Quad (2.5 GHz quad core). I use this computer as a portable spare and for teaching technology classes.
I have not had any problems with the CPU overheating or the fan dieing.
As far as I remember, it was simple to install on the motherboard.

5 out of 5 eggsSame old same old

Pros: It's a fan. It cools a little bit better than stick, it looks a little bit better than stock, and it's cheap. The fan assembly itself comes off the heat sink so it and the block can be cleaned easily. Cord is sleeved to keep it tidy.

Cons: None really. It's simple and it does what it's supposed to.

Other Thoughts: It's been sold exactly as it is for years and years. It's a good ol' standby at this point.

5 out of 5 eggsAnnoying to mount.

Pros: Sturdier than the Intel piece of garbage.
Preapplied thermal compound.
Does what it advertises, keeps the CPU cool.

Cons: Annoying to mount, not worthy of an egg deduction though, since it is just how it's made to be.

Other Thoughts: Without a doubt better than the Intel cooler, but it probably won't raise any eyebrows with its performance, as it's only a notch better than the Intel ones. However, this cooler is just so much more durable than the Intel stock heatsink that it surprised me.

I did hate the mounting method for this, I know I willingly bought myself into it, but I just hate this style of mounting in general.

2 out of 5 eggsNoisy

Pros: Seems to work OK.

Cons: Emits a fairly loud and unpleasant low pitched droning sound all the time. Sounds like a cheap toy. Very unattractive.

Other Thoughts: I haven't returned this item since the computer it is installed in is used by a person with poor hearing. Otherwise, I would have returned this immediately.

4 out of 5 eggsGreat for the price.

Pros: Very good for the price.
same base profile as OEM, just taller and copper core.
Installed easily in socket 1150.
The mounting brackets were better then Intel stock

Cons: Loud
5-10C hotter then Cooler Master Geminii M4 w/ Intel I3 4370.
I5 OEM heat sink had similar performance but was quieter.

Other Thoughts: I wear headphones most of the time, so noise is not usually a concern for me, but it is still noticeable. I can hear this fan when I walk past my office. I am using an Intel I3 4370, and it mounts just fine to the 1150 socket, but for my build it is not quite or cool enough, I did like the profile, and maybe in a quieter case it would be nice. It is a cheap replacement for an OEM heat sink, but I need something different.

5 out of 5 eggsCPU Fan for CHEAP!!

Pros: for 10.00+ free shipping its awesome. I was cleaning the case of an old c2quad and broke off one of the secure pins from the original fan. It produces the same temps as the old intel lump of metal.

Cons: Nothing

Other Thoughts: If i was going to cool a 1150 or better i'd pick a better fan for a little more.

3 out of 5 eggsDidn't really do anything.

Pros: *It works
*It looks nice
*Pre-Applied thermal paste

Cons: *The push pins are super hard to actually get pushed in
*It didn't lower temperatures at all compared to the stock Intel cooler

Other Thoughts: It didn't lower temperatures at all. I wasn't expecting my CPU to be at 20 degrees or anything, but it might of actually raised temperatures.
