Simple, functional fan 10/26/2019 9:58:59 AM

Pros: - Easy to install
- Cheap and functional
- Came with thermal paste already applied

Cons: - It was a bit tricky not to get the paste on anything

Overall Review: A nice little fan that helped me out in a pinch. It went in easily, works well, and my CPU is happy. I appreciated the simplicity of the thermal paste, even if it was a bit of a pain.

works just great 1/14/2019 6:20:59 AM

Pros: Doesn't have the irritating growl of the stock cooler that drove me crazy and got me to buy this one
very easy to install, just snap the pins in. comes with thermal paste already applied.
Lower profile than the stock cooler. Copper base plate.
Fits all recent mainstream Intel sockets released after LGA775.

Cons: Nothing, this is perfect for what I wanted. an inexpensive, low profile QUIET alternative to the stock cooler, which has now been relegated to the dung heap.

Overall Review: using with a Core i3 4170
if you have a Core i9 9900k, keep shopping

Brilliant designs need little improvement 7/15/2018 9:49:37 AM

Pros: Good cooling in a small package with super easy pushpin installation
Easy on the eyes, no weird, non-functional gamer-chic design elements
Incredibly cheap
Inaudible at low PWM settings

Cons: Fins bend easy, although I only had one get out of place
Pre-applied thermal paste is junk (although pretty much any pre-applied will be)
What's with the Z sticker? Where's the Z in Rosewill? Rozewill, maybe?
Some of the specs are misleading/out of date
Really gotta press down on the pins to get em in there

Overall Review: This little dude is pretty neat, I got it for a super small form factor build where my graphics card partially hovers over my CPU on a PCIe riser so space is really at a premium. The specs sheet suggests that this thing will be 54mm tall which is wrong, it's quite a bit shorter (pcpartpicker lists it at 30mm) and it doesn't list 1151 compatibility but trust me, it fits. This is because this thing came out in 2010 (!) and the 1151 socket was introduced in 2015. Intel's been using the same cooler dimensions since the beginning of time so this isn't an issue. The thermal paste that comes pre-applied is worth replacing, it's very thick and I was idling at 50C on a Celeron. Cleaned it up, reapplied, and now I'm in the 30s, I think I might try again and see if I can get even lower. At higher RPMs it definitely whirrs a bit but I didn't find much increase in cooling so I have it set on my BIOS's silent setting and it's dead quiet. This design is pretty elegant, enough so to still be effective after 8 years on the market. You should expect near-comparable performance to more expensive and complex models (I won't name names) at a small fraction of the price, not to mention with the simplest method of installation out there.

For those still reading, here's a little on WHY this keeps pace with performance options. When you're less than 5 centimeters away from the CPU, anything you do to move heat away isn't moving it very far, making copper vapor pipes less effective than they normally are in tower models. This makes dissipation more important, which you only need fins and a fan for. The copper core is as effective as it gets at picking up heat from the CPU, which is efficiently distributed to the aluminum fins because of their radial orientation. Rosewill fans are made by third parties, some of which are top of the line (like the Hyperborea case fans) and it seems like this is one is among them. Finally, since this and other heatsinks in this range are all limited to processors with a TDP of 65 watts or less, they're not making that much heat to begin with. This means that at a certain point, adding more heatsink mass has diminishing returns: the larger heatsink can hold more heat than the processor will ever generate, while the larger size becomes tougher to cool with a small 80mm or 92mm fan and also adds substantially to the price. This guy hits the sweet spot of all these variables which is why it excels.

Horrid information. 12/19/2017 8:18:32 PM

Pros: Looks nice.
Feels good to the touch.

Cons: As a brand new pc builder I assumed "Oh any old CPU cooler should work, it's just cooling it should be cheap". I could not have been father wrong. With a measly max TDP rating of just "65" I found out it could not hope to properly cool down my "95" Watt I5-2400, NOW THERE IS NOTHING WRONG WITH THIS..... Except... IF YOU'RE BRAND NEW TO PC BUILDING YOU'D HAVE NO IDEA. This isn't just an issue with this cpu cooler but most, The Max TDP Should be in bright big bold letters in the description with a little description of what it means for example: The "Rosewill RCX-Z775-LP 80mm Sleeve Low Profile CPU Cooler" has
a Max TDP of "65" watts, TDP is amount of heat generated for your Processor meaning if it's over 65 watts (Check on the manufacturer's website) this will NOT work. This is why I'm knocking off three eggs, 13 dollars wasted. Every single PSU should have that exact same description modified to their own TDP. The fact this one one as well as MANY others do not list their TDP is very obnoxious. In-fact the TDP should be listed in the title of the item rather than "Rosewill RCX-Z775-LP 80mm Sleeve Low Profile CPU Cooler" it should be called "65TDPRosewill RCX-Z775-LP 80mm Sleeve Low Profile CPU Cooler". Never tried it out to see any other issues.
