OcUK H²Flo Extreme Liquid Dual Fan CPU Cooler (Socket LGA1366/1155/1156/775/AM2/AM3)

The OcUK H²Flo EXTREME Liquid CPU Cooler is a fantastic product aimed at high end CPU cooling, with the power to slay any overclocked CPU temperatures succesfully. The cooler houses a large surface cold copper plate to ensure all the heat is drawn away from your CPU and transferred to the sealed liquid and the pump then transports the liquid round to the dual thick radiator which then cools the liquid back down to enable the liquid to recirculate back to your CPU block to again pull more heat away. All you need to do it add a fan of your choice to the radiator and your CPU will be cooler than the next Ice Age.

- Socket LGA1366 / 1155 / 1156 / 775 / AM2 / AM3
- Radiator Dimensions: 120mm x 152mm x 38mm
- Fan Support: 120mm x 38mm x 2
- Double-thick 120mm radiator for increased surface area and cooling potential
- A new improved micro-channel cold-plate design more efficiently transfers heat
- Quick and easy installation brackets make it easier than ever to upgrade to watercooling.
- Cold Plate: Copper
- Radiator Material: Aluminium
- Thermal paste is pre-applied

Easy when you know aow

Excellent product just don't be fooled by the other reviews it does not come with a 120mm fan like the Corsair H60 and don't watch the video demo because all you will see is a fat American, you will understand it much easier to install your Intel/AMD build if you read the PDF file in the downloads section of this link.
it will make it much clearer for what bits to use where.
Again very good at what it does just please read this first and save your self the stress and the headache.

Oh and thanks for the Haribo OC

Excellent GPU Cooler

Purchased this when on special offer and it is a brilliant GPU, ahem CPU cooler for the money.


Julian Vicari 2012-06-06

Pretty Good

Replaced a perfectly functional Noctua NH-U12P SE2 for absolutely no good reason!
Cooling is comparable, though the new cooler gets the edge when CPU is under full load maybe 5-10c lower. Keeps an i5 2500k over clocked to 4.5 with a core voltage of 1.33 in the low to mid 50's stress testing with Prime95.
I used the fans from the Noctua, runs pretty well silent, the pump runs as good as silent too.
As others have already said there are no fitting instructions, not a problem as it's a fairly simple affair. Just look on YouTube for fitting a corsair h50,60,80 or 100.

Works Great

No instructions included, but since it's the same as the Corsair H60, I just followed the instructions on the Corsair blog.

Slightly tight squeeze inside my case - it actually obscures the bottom fan of the PSU a little bit, but that's just a problem with my specific setup.

It's very quiet (basically unnoticeable, even at full load), idle's at <10C over ambient temperature, and steady at 50C with Prime95.

easy fix on AM3

No instructions with this. Fitting to AM3 is a breeze (which I realized just before support answered the phone)
Remove the fixing brackets from the cooler block and replace with the 2 U shaped ones in the kit. Use the 2 key shaped screws and the thumbwheel nuts to fix where the heat sink clip normally attaches.

CPU temp down to 50-51 on load now

Don X 2012-05-25

one too shabby

Well i expected a drop from stock cooler temps but wow, under aida64 at 100% load stock temps rose to 85 within 5 mins.

With my all in one there maxing at under 50 after more than half an hour, stable and bored :-> running two Akasa AK-191-BL Blue Ultra Quiet 120mm Fans in push pull.

The whole thing is noticeably quieter than stock cooler despite me going from IGPU to a HIS 7850 at the same time.

Gavin 2012-05-16

Good stuff

Nothing bad about this product. With good fans it is just perfect. Surprisingly WAAAAY better than Corsair H80! It's quieter and cools much better. I know. Hard to believe.
I post a proper, unflattering review about H80 as well.

Rafal 2012-05-16

Absolutely Brilliant!

I fitted this last night and my temps have already dropped by over 20 Degrees!

Was a little fiddly trying to fit it as the pipes are a little stiff but otherwise it's an absolute dream.

Very Happy and would definately recommend!

Mr M. Lewis 2012-05-16

Amazing little kit

First of all big thanks to ocuk for quick delivery, free pack of haribos xDD and a wine voucher :P

its OEM so no manuals, ive spend 30mins trying to figure out how to mount it on a am3 but eventually got it to fit :P works amazing and for such price(

Matt 2012-05-11

Top Stuff

Now I'm well happy with this, it came bundled with the system purchased (didn't realise) so when I noticed it I was shocked and curious all at the same time. so far highest temps I've seen on the CPU is 21c that was during gaming, on average temps hover around the 9c mark. lowest temps I've ever had on a system!
