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.

1 out of 5 eggsWon't secure to Asus P8 H61-MLE

Pros: None.

Cons: Cheap plastic pins do not secure to an Asus P8 H61-MLE, rendering the heat sink completely worthless for its advertised purpose.

Other Thoughts: Skip it. It's useless.

4 out of 5 eggsIt does the trick, but be careful...

Pros: - Kept Pentium G3258 under 50C when playing games like Arma 3, BF4, and Dota 2.

Cons: - One of the pins that keeps the heatsink held tight broke when I took it off to upgrade my CPU.
- I have to use stock Intel cooler now.

Other Thoughts: At least I have a another case fan now.

1 out of 5 eggsLooks Great But....

Pros: Well constructed (except for plastic mounting post inserts). Fairly quiet except when fans ramp up to max.

Cons: Retainers do not snug cooler to processor well so carefully monitor CPU temps after installing..

Other Thoughts: Installed this on an ASRock Pro4 mATX 1150 board using an Intel i3-4150 processor. Even after ensuring posts were rotated opposite the arrow (just like the intel cooler) and pressing till seated, the cooler never seemed to fasten snug to the processor. Upon startup on day 2 of use the temperatures steadily climbed into the mid 90 C range at which time I shut the machine down. During inspection of the cooler I noted it was barely making contact with the processor and could easily be moved. Posts were still seated but apparently the motherboard is too thin for the plastic rings on post to seat and pull cooler snug to processor. That said, the cooler does look more than up to the challenge of cooling but like some other negative reviews, it can't always secure to board properly. If someone had a little time I am sure they could fasten it securely using some screws, washers and nuts but really, it should work properly out of the box. Needless to say I could not use this cooler so I swopped it with a factory i7-4790K cooler, left over from another build, which has a copper core - unlike the i3 cooler that came with i3 processor which is all aluminum. Now working temps around 41 C, motherboard at 33 C when room at 75 F.

1 out of 5 eggsNot Impressed

Pros: None, really.

Cons: LOUD. Vibrates something fierce.

Other Thoughts: I bought this to replace an aging heat sink/fan on an old LGA 775 Pentium 4. I replaced it because the cooler I originally installed was beyond the point of cleaning and it had also been in use for the better part of 8 years and got pretty loud. So I got this in the hopes of minimizing the noise a bit without breaking my wallet for an ancient non-mission critical CPU that is still somewhat in use, believe it or not. Once again, I've proven to myself that when it comes to PC tech/hardware, you get what you pay for...

1 out of 5 eggsVery loud

Pros: Cheap, looks decent

Cons: This fan is super loud. It makes my pc sound like a jet engine. This is also extremely difficult to assemble with the motherboard.

Other Thoughts: You get what you pay for. Hence it was my mistake to purchase this fan.

4 out of 5 eggsInstall It Right

Pros: Works well. 25C at idle, i5 2500
Good price 95 W rated

Cons: Needs some patience to install. 5 - 10 min.

Other Thoughts: Set the anchors to the locked position. Place cooler, line up anchors in holes. Check your using the right holes. 1155 or 775 etc. Double check it . Hold the metal bracket of cooler tight to Main board. Push the top of anchor in the locked position, down. Then diagonally the same to each anchor. The 1/4 turn release is only used for the removal of cooler.
Check all 4 are tight, not just 3.
