Antec Kühler H20 620 Liquid Cooler Review

Today we are using the latest Intel Core i7 990x Extreme Edition processor which we reviewed a short while ago. This is the current mainstream flagship processor from Intel.

While we could use an open test bench, we like to try and mirror more ‘realistic’ conditions, so we have built the system inside an Antec Twelve Hundred chassis. Room ambient temperatures are maintained at a steady 20c throughout testing. We use diodes to measure core temperatures.

Intel System:
Processor: Intel Core i7 980x
Motherboard: Gigabyte X58 Assassin
Thermal Paste: Noctua NT H1
Power Supply: Corsair TX850W
Chassis: Antec Twelve Hundred
Memory: GSkill RipJaws DDR3 2000mhz 6GB 7-8-7
Graphics Card: Sapphire HD5670 Ultimate Edition

Comparison coolers:
Corsair H50
Corsair H70
Coolit ECO A.L.C.
Coolit Vantage A.L.C.
Noctua NH D14

All other coolers were set to their default fan speeds for this section of the review.

The Kühler falls in right behind the Noctua NH D14, which is impressive, outperforming the Corsair H70 at ‘low' default fan settings.

We are overclocking the Intel 990x to 5ghz on this board with the core voltage set to 1.5, extremely high levels and a quick way to judge ultimate overclocked cooling performance.

Great results from the Kühler H20 620 cooler and almost neck and neck against the Corsair H70 with fans set to high.

  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.
