Corsair H55

Not too bad, but not too good.

Posted by HowManySmall on October 21st, 2016
Your PC will run cooler and quieter when you replace your CPU’s standard heatsink with a Hydro Series H55.
Installation is straightforward: if you can get to the back of your PC’s motherboard, you can install an H55. All you’ll need is a screwdriver.

I had to trade a Dualshock 4 to my friend to get this thing. Here's hoping it doesn't leak!

Test System

  • CPU: AMD FX-8350 (overclock: 4.6GHz@1.49v)

  • Motherboard: ASUS M5A97 R2.0

  • Memory: Kingston HyperX FURY 16GB

  • GPU: Sapphire R9 280X Tri-X TOXIC@1.2/1.7GHz

  • Case: Cooler Master HAF X

  • PSU: Corsair HX750

  • Software: SpeedFan / Prime95 / CPU-Z / Windows 10 Professional

Installation

Getting this thing on was a task because my friend who lent it to me didn't include the backplate. I had to zip-tie it on, which you can see in the photos below, and that's not easy when you're using a full tower, in a cramped space, and you're kind of a small person. So I'm not biased about having to zip-tie it on, I asked my friend to rate installation out of 10, and he gave it an 8. Otherwise, this thing would've gotten a big fat zero.

Noise Level

When I ran two fans on this thing (the stock fan and my CRYORIG QF120), and even then, it was still really, really quiet. I mean, it's not as quiet as the Macho X2, but damn, it was still really, really quiet. I couldn't hear either of the fans, the pump, or anything. I'll give this thing a 10 for not making a sound. Good freaking job Corsair/Asetek, I'm glad I didn't have to hear the pump.

Performance

Okay, so here's the part that took me the longest to measure. I had to install it so many times, and that took a good 3 hours of my time alone, but here are the benchmarks:

Idle

Stock

  • Minimum: 24.0°C

  • Maximum: 33.0°C

  • Average: ~31.2°C

Overclocked

  • Minimum: 27.0°C

  • Maximum: 35.0°C

  • Average: ~33.5°C

Load

Stock

  • Minimum: 41.0°C

  • Maximum: 48.0°C

  • Average: ~47.0°C

Overclocked

  • Minimum: 54.0°C

  • Maximum: 82.0°C not sure what happened here.

  • Average: ~62.4°C

So, yeah, pretty passable numbers for a 27mm single rad. I'll give this a 8.5 here, mostly because it's performing how I suspect a 212 EVO would, but it costs $50 at the time of writing. It'd be a 10 if it was less than $40USD, as I do consider price/performance.

Aesthetics

When my friend gave this to me, my first reaction was that it is so much better looking than my old Alienware CLC (ugly, ugly corrugated tubing). I really liked the tubing as it's smooth and not corrugated. Smooth tubes are B-E-A-UTIFUL. This simplistic cooler deserves a 10.

My worst picture. You're lucky you don't see it.
This is probably my worst picture ever. Yuck.

Closing

So, this was a new experience for me. I've never once in my life used a liquid cooler that actually fit my socket, and was sold by someone I know (like Corsair, NZXT, be quiet, Fractal Design, etc). I felt pretty special installing something with zip-ties, even though it's been done so many times before.

Scoring

  • Performance (40% of the score): 8.5

  • Noise Level (30% of the score): 10

  • Installation (20% of the score): 8

  • Aesthetics (10% of the score): 10

  • Final Score: 9 / 10
