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.

4 out of 5 eggsGreat!

Pros: -Quiet (When not at full speed)
-Red
-Rosewill quality

I really am amazed at this thing!

Cons: Can be a bit loud at full speed... I have it cooling my i5 3570k, and only when I'm playing BF4 on highest settings does it go to full speed, and it can get a tad bit noisy, but definitely quieter than stock.

Other Thoughts: I really do like this cooler - Probably will buy in the future.

Pros: Price. Red. Quiet

Cons: N/A

Other Thoughts: Bought this to replace an aging heatsink/fan which still worked, but was loud. Slapped this into place and was surprised at how quiet it was.

5 out of 5 eggsExcellent product

Pros: Awesome looking red and black fan. Copper core. Very quiet. Easy to install. Compact… does not require a lot of extra space around the CPU socket to mount. Works with a variety of processor sockets.

Cons: None so far

Other Thoughts: This is the best CPU cooler I have ever purchased for under $20, and actually performs better than just about any fan-based cooler I have ever used, regardless of price. The only time I can even hear it running is when I am really taxing my system hard. Even when it does rev up, it is quieter than most fan type CPU coolers I have used. It was painlessly simple to install and has worked perfectly since the moment I started using it.

The one thing I don’t understand after reading some reviews for this product, and other push-pin mounted CPU coolers, is why some people have so much trouble figuring out how to mount them. I have been building and servicing computers for many years now, and have installed/uninstalled these push-pin type coolers countless times. So far, I have never had a problem with breaking them or not getting them to stay put. There is no “twisting” or “turning” (as some people have stated) of the push-pins required for mounting. The pins simply have to be in the up (unlocked) position and rotated fully clock-wise (opposite direction of the arrow) before mounting. Then you simply align and insert the tips of the pins in the mounting holes on your motherboard and gently push them down until they click. The only time you should ever have to turn or twist the push-pins is when you dismount the cooler.

I hope this helps.

5 out of 5 eggsCPU runs 15 degrees cooler

Pros: Thermal paste already applied. Easy to install. Lowered Temps by 15 degrees compared to stock fan. Happy with it.

Cons: Was loud when I first installed it. Figured it had something to do with overclocking and my old fan. Had to change some settings around in the bios.

5 out of 5 eggsQuiet and Affordable PWM

Pros: Affordable, PWM, Low Profile, Easy install.
Super quiet ~700 rpm at low load/idle. Cools well at high load at ~2400 rpm.

Cons: Can be loud at full tilt, but that should be expected with it spinning at ~2400rpm. So not really a con, just a fact. Keep in mind, if you don't have/turn on automatic fan control it will spin constantly at full speed. Pretty much all coolers will do the same.

Other Thoughts: I've been in the process of changing one of my old systems into an htpc/nas box. I got this to replace a massive 3 pin Zalman cooler that was unbearably loud ( I couldn't find the manual fan controller for it.)
I adjusted the settings in the bios for automatic fan control and this thing is super quiet at idle and while watching movies, which is when a silent fan really counts. Temps while watching movies using the cpu/software decoding (gpu decoding turned off to save power/noise) are ~50C which is fine by me.
I haven't done much gaming on the system yet, but I did some cpu burning and the temps were steady at ~75C after about 15 min.
All in all for $15 I'm very happy with this.
