Antec Kühler H20 620 Liquid Cooler Review

Today, we are using the high end Gigabyte X58 Assassin motherboard which we reviewed last week, you can read this review over here.

The Assassin motherboard is one of the finest products we have reviewed this year, and is a worthy partner for a liquid cooling system, especially as the overclocking options are so comprehensive and detailed.

The adhesive backplate is attached without problem and four metal bolts are passed through to the front of the board. There are a possible twelve positions as can be seen in the images above. This is to cater for various slot sizes.

As we are using an Intel 1366 motherboard, the blue offset clips are used with the retaining mount system, as seen above. This retaining ring should be left in a loose position so the main cooling head can be inserted under it and then rotated into a locking position. This is a very similar method to the Corsair H50 and H70 coolers of yesteryear. It is a little fiddly, but doesn't really cause any issues.

This stage of the process will be dependent on your choice of chassis. Above, the Antec Twelve Hundred case requires a rear mounted exhaust fan to be removed.

As these fans are fed into a rear fan control section for speed adjustments, we need to cut one of the cables. Not ideal, but necessary.

This fan is then attached into the 120mm location. Antec recommend the fan is locked into an exhaust position so warm air is expelled from within, keeping the traditional air flow mechanic in place. As some of you may remember, Corsair wanted the H50 and H70 fans to be mounted in an intake position, therefore pulling in cool air over the radiator. The idea was fine in theory, but we didn't think it worked well within the typical airflow of a normal chassis design.

When the radiator is fixed then the cooling head can be twisted into position underneath the retention block. When completed, then the four screws can be tightened to maintain good clamping pressure.

Installation took about 15 minutes the first time, but would take less on subsequent reinstalls.

  1. £45, damn thats a hell of a price, its 20 quid less than the D14.

  2. Thats a really good looking product, no doubt about it. the price is amazing. i thought it was £65, same as H70.

  3. I was waiting on a few good reviews of this. I think this will be my next purchase. I still have my H50 from when it was released and its a bit tattered looking now.

  4. I think antec hit the price spot on. a lot of people who normally wouldnt spend 60 quid on a cooler will go for this due to the 45 quid asking price, same as frio, but smaller and better. seems like a win win

  5. Very impressive cooler for the money. The thicker hoses are definitely helping.

  6. ordered one online for £42, thats a hell of a bargain as you say.

  7. Good review, great cooler. Just to let you know, there is a small typo in this article on page 2 – ‘ships with mounting brackets for both AMD and Nvidia platforms’.

  8. The thing sucks – three time as expensive as a simple Corsair fan system and twice as loud. There is no way to control the RPM, it will constantly be over 1400. I just got this thing installed and it is driving me mental.

    I implore you not to buy this piece of crap.
