Antec Kühler H20 620 Liquid Cooler Review

Recently we have changed our method of measuring noise levels. Ambient noise in the room is around 20dBa. We measure from a distance of around 1 meter from the chassis and 4 foot from the ground with our Extech digital sound level meter to mirror a real world situation.

KitGuru noise guide
10dBA – Normal Breathing/Rustling Leaves
20-25dBA – Whisper
30dBA – High Quality Computer fan
40dBA – A Bubbling Brook, or a Refridgerator
50dBA – Normal Conversation
60dBA – Laughter
70dBA – Vacuum Cleaner or Hairdryer
80dBA – City Traffic or a Garbage Disposal
90dBA – Motorcycle or Lawnmower
100dBA – MP3 player at maximum output
110dBA – Orchestra
120dBA – Front row rock concert/Jet Engine
130dBA – Threshold of Pain
140dBA – Military Jet takeoff/Gunshot (close range)
160dBA – Instant Perforation of eardrum

Generally this is a quiet fan, generating very little noise, even when partially loaded. Often it will idle around 30 dBa, peaking at 34 dBa when stressed or cooling an overclocked processor with increased voltage. It is significantly quieter than the last generation Corsair products.

  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.
