Rosewill RCX-Z775-EX 92mm 2 Ball CPU Cooler

  • 800-2100 RPM
  • 16.5-46.2 CFM
  • 3 heat pipes, Copper base
ICON Loading...

A compact tower with three U-shaped heatpipes running through a powerful stack of aluminum fins, the Rosewill RCX-Z775-EX is a chilly champion, banishing heat to the outer reaches of your case! Designed specifically for your Slot 775 system, the mounting bracket is integral to the unit, and the pipes the bent outwards, offsetting and balancing the weight of the unit when it's installed.

The mirror polished copper base attaches smoothly to your unit, and the included thermal grease can further improve the cooling efficiency. The 92mm fan is clipped into place, or can be replaced with anything of a compatible size. You can aim the Z775 wherever you need it most, but usually pointing it toward the rear exhaust provides the best results.

This is a spectacular assembly both in looks and efficiency, ready to keep your system in the hottest situations. Keep cool with Rosewill's RCX-Z775-EX!

  • newegg Excellent Cooling The Rosewill RCX-Z775-EX features a copper base and three copper heatpipes for optimized heat transfer and a 92mm fan for excellent cooling performance.
  • newegg Fan Speed Controller The bundled PWM fan speed controller provides easy control of the noise level and fan speed for exceptional cooling and quiet operation.
  • newegg Back Board Design The Rosewill RCX-Z775-EX features a back-board installation design for more support to the motherboard and thus avoids damage.

5 out of 5 eggsGreat cooler

Pros: Runs my OC'd E8400 (dual core Intel 3.0 to 3.5) 100F at idle, and never peaks over 130F on full load. I keep my room pretty warm, as well, so it does a fantastic job.

Cons: none, had it for over 5 months.

Other Thoughts: I've used a few coolers on this processor (even stock). This is by far the best one I've used. The stock would idle at 120, and get to full load at 150-160F (without OC'ing). This cooler is fairly large, however. But it without a doubt gets the job done like a pro.

5 out of 5 eggsNo complaints at all

Pros: This unit is made from high quality metal. They include thermal paste so don't bother buying extra. Instructions and installation couldn't be easier.

Cons: Just be aware that this is a large cooler. So you should measure the distance from your CPU to the other side of case to make sure it will fit.

Other Thoughts: CPUID Hardware Monitor reports my system temperature running around 78F at idle, and a max of 110F while gaming. I also have 5 case fans in my rig to extract the heat.

5 out of 5 eggsvery happy with the cooler

Pros: Efficient and silent. I replaced a damaged stock cooler on a Q6600; that cooler had plastic supports which damaged very easily and lost tight contact with the CPU; the Rosewill's contact is very firm and the temperature on the CPU is around 30 deg C (casual use, no O.C.) @1400 RPM, no noise (and I have a fanless GPU).
Recommended.

Cons: None, if you can live with having to unmount the MB to install the cooler (5-10 minutes).

4 out of 5 eggsNice, but...

Pros: My machine shut down twice in the past 24 hours using what I thought was a good MassCool product. I do digital and film to digital photography and start with large images. I batch them from TIFFs to JPEGs using a batch converter, and it really puts a strain on the CPU. Changing from the MassCool to the Rosewill kept idle temps the same, but full load temps dropped almost 10 degrees C. Not bad. And this is before the Shin-Etsu paste has had a chance to work in properly. The bottom plate is smooth and not grooved like most copper bottoms are, so there is probably less need for the compound to work into gaps and striations. BTW, I am running a Socket 775 P4 CPU, 640, 3.2G 1M/800 and they run warm anyway. I had to 'detune' the CPU from 3.8G to 3.3G with the MassCool, I am clocked back up to 3.8G and running as cool as at 3.2.

Cons: INSTALLATION!!!!!!!!!! Jeeze! You can't install the fan and then install the whole assembly. The fan is not easily attached to the heat sink, and I wound up breaking one of the 'ears' that hold the fan in place. It still snapped in place well and is held in firmly in place, and seems to be doing a good job.

Other Thoughts: I paid $39 for the MassCool when it first hit the streets, and I thought that was a good price. $29 for this one, even with the fan installation quirk is a good price for a cooler that can keep my overclocked CPU this cool. I would recommend this, just be aware of the fan mounting issue. BTW, I used the bottom piece from the MassCool, it has the same threads as the Rosewill so I didn't have to disassemble the whole system to install. That was a big plus.

5 out of 5 eggsGreat Upgrade

Pros: Easy Installation. Actual Screws + Backplate make it a breeze to install, even if the backplate is plastic. The backplate comes complete with a little sticker tab, which adheres it to the motherboard while you screw down the unit itself, making it even easier to install. As always, never work on your computer on carpet, and use only the smallest amount of silver when applying to the chip.

Cons: None as of yet. Idle temps are at 32c while temps after 2 hours of L4D2 only spiked it to 55c. Very very pleased.

Other Thoughts: Super shiny metal makes it look good in any case with a side window. Do yourself a favor, do not buy an cpu fan with plastic push-tabs instead of screws and a backplate. They are garbage compared to this beauty.

1 out of 5 eggsi question the specifications

Pros: nice box. heatsink is installed in a matter of seconds.

Cons: ok...this heat sink under specifications from newgg. says it will work with any intel core 2 extreme/quad/duo... ya da ya da. i bought this, installed it, and it makes my cpu while IDLE. run on average 55C...uhh no, i dont think. while playing a game? i get 75C...i dont think so. something is really wrong here. i know how to install a heatsink dont even go there. my question is.. on the box itself from rosewill. it says it will work with an intel core 2 duo socket LGA 775... an intel core 2 "QUAD" is also LGA 775. but the box of the heat sink says nothing about it working with my intel core 2 quad. so are these specifications the ones that will work "WELL" with this heatsink? or just the compatibility that rosewill forgot to put on there that this heatsink works with intel core 2 quad. either way. i get heating problems through the roof. i'v alrady had to underclock my processor. i had to turn 1 core off. im about to turn off another one to maintain temp status...

Other Thoughts: i already have one of rosewill's cases great case. but sorry rosewill...this is a junk processor. if i could get that question answered that would be terriffic. im sure others here would like to know. is this heatsink designed for a intel core 2 duo like you have illustrated on the box under compatibility. or it also works with intel core 2 quad. of course it works with both. but is this heatsink designed to pull the amount of heat the quad makes away from the cpu itself, verses the intel core 2 duo?

Manufacturer Response:

Dear Valued Customer,
Thank you very much for purchase the RCX-Z775-EX. The problem might be due to either a defective unit or a problem with the thermal paste. Please try removing the cooler and clean the thermal paste off by using lighter fluid and coffee filter. Apply new thermal paste and install the cooler. This should solve the heating issues. There is a link below that Newegg made showing how to do it. If you are still having problems, please kindly contact Rosewill support team either via phone at 800-575-9885 or via email at rma@rosewill.com so we may assist you with a replacement. We are eager to assist you in any possible way. We look forward to hearing from you soon.
Thanks,
Rosewill Customer Care
