Product Description

The Corsair Cooling Hydro Series H50 high-performance CPU Cooler is quiet, easy to install and outperforms even high-end air coolers. You get superior cooling for improved overclocking performance without the complexity of traditional water-cooling systems. The simple, closed-loop design delivers the power of liquid cooling and the ease of installation of traditional air coolers. The H50’s small size lets you enjoy a less crowded case with better airflow, and you can use the included ultra-quiet, high-efficiency 120mm fan or simply connect the radiator to one of your existing case cans. Air-based CPU coolers simply aren’t as efficient as water coolers, and can take up too much valuable space. The compact, closed-loop Hydro Series H50 takes your CPU’s temperature to new lows and takes up less room doing it.

As I was researching heatsinks for my new i7 setup, I cam across a few all-in-one water cooling kits. After a short time looking at reviews, it was clear that this was the best of the bunch as far as all-in-one water cooling kits are concerned. What really drew me towards this unit, is the size and weight. After using a TRUE Ultra 120 Extreme in my last setup, I was weary of buying another due to the size and weight. You can actually see the heatsink slightly bending the motherboard when the case is stood up. Not only that, the heatsinks are huge! So big in fact, I had to remove a 120mm fan just to get it to fit in an 830 stacker case. Also, there is much less room to work with when installing one of these huge heatsinks.

So after using the Corsair H50 for a month now, here are my thoughts:

Pros: Very easy to install, light compared to heatsinks, easy to work with in the case since it is smaller than a heastsink, radiator is small enough to work with as well, and great temps(see below for specs & temps)

Cons: Liquid in the case has always scared me, but Corsair gives you a two year warranty and I have read on their forums that the pump in these things will last for many years past the warranty. Possible leaks, but again, Corsair says this thing will not leak and after looking at how the thing is put together, I believe them. At least it won't leak in the lifetime you have it in the system.

Other thoughts: The directions tell you to pull air in from the case by mounting the fan/radiator to the inside back of the exhaust port. I actually did it different. I had it in a push/pull configuration. I push air from the inside, through the radiator and then pull the air through with a second fan on the outside of the back exhaust port.

Great product for people who need high performance cooling in tight spaces such as MATX HTPC cases. Unit is also VERY QUIET!! Performance is equal or greater to a high end air cooler.

The Corsair H50 was installed into a nMediapc HTPC-8000 wooden case cooling an AMD Phenom II X4 955 overclocked (3.7ghz) processor.

Keeps my Q9550 idling at 36 degrees C and I'm hitting 60 C under sustained full load using Prime95. Vcore is set to 1.38 volts and with a 482 mhz FSB x 8.5 multiplier I'm running at a rounded 4.1 Ghz. Using my old Zalman copper air cooler I would hit about 85 degrees C running Prime95 at 3.6 Ghz and 1.3 volts so this is a huge improvement.

The instructions in my box were not the best and could very much be improved upon for someone with little system building experience. I've been building my own for some time now so it was no big deal to have to remove the motherboard to get the back plate on and figure out how the mounting bracket works. Thermal grease supplied didn't seem like it was quite enough so I put a very thin coat on the CPU itself to ensure having even coverage.

the best cooler you can buy actually, just save your effort and the space needed inside and buy this cooler, on i7 920 @ 4.0 GHZ idle is 49 to 50 c and load is on 72 - 74 c , knowing that i live in egypt and its really so hot in here, yet this cooler is amazing, make sure u have enough ventaliation in your case.

I'm using this cooler on an i7 chip in a gaming rig.. I mainly settled on the closed loop water cooler since I didn't want to fight a large air cooler that may or may not fit in my case. Overall, this device was easy to install and keeps my temperatures quite low, even during intense gaming.

For my own purposes, I replaced the stock thermal paste with Arctic Silver (I rarely trust manufacturer paste), but by the looks of the stock paste, it may have performed just as well and doesn't look like it is globbed on.

The only difficulty I had was that the tubes are quite rigid and due to the design being closed loop, are fixed length. Due to this, the orientation of the fan in my case almost put alot of pressure on the tubes, but nothing to cause a kink or difficulty.

Overall very impressed with its cooling capabilities, it really does outperform even the best air cooler i've used in the past, and the best part is it is very quiet vs the air coolers, and does not take up 2/3 of my case!

I've been gaming and tinkering with computers for a long time, and I thought it might be fun to finally try some overclocking. However I needed to get my temps down before I could even consider it. I was initially going to go with a nice big aftermarket Air Cooler, but my case is only 7.3" wide, so my options were were very limited. I chose the H50 because of all the positive reviews, and its dimensions fit inside my case. The installation took some time, as I had to remove my video cards and motherboard, but was overall a breeze with the instructions and online videos provided by Corsair. I would recommend taking measurements prior to purchasing to be safe, as even though this is a compact cooler, it still was a tight squeeze in my case, and just grazes the bottom of my PSU.

How much difference did the H50 make at stock clock speeds? (Room Temperature 70F or 21C)

With my stock cooler on an i7 920, I received a peak temperature of 87C after 1.5hrs in Prime 95 and 75C under a heavy gaming load.
With the H50 I received a peak temperature of 64C after 1.5hrs in Prime 95 and 61C after 1.5hrs of heavy gaming load (BFBC2)
These are the occasional high peaks. My normal H50 temperatures in game are low to mid 50's and in prime 95 usually hovers right at 60.
Idle temps low to mid 30's

However to achieve these temperatures I did not have the H50 in the recommended configuration. I originally set the provided fan as an intake per Corsair's recommendation, and received a peak of 71C in prime 95 and 68 under a heavy gaming load. My memory temps also spiked from all the extra hot air in the case. The problem was in my situation, the exhaust from my 2 video cards and PSU were welling up behind my case and getting sucked into the H50's intake.
