Super silent and soooo easy to install

A fan on my PC started to click, so I knew I had to change it.After a bit of research I found that these were the best option, they may not be the cheapest, but they're well made and are super silent.They arrived quickly (as an aside - great packaging). They were really easy to install, just four screws and a plug and I can honestly say I should've bought them years ago. They're totally silent and they've made working next to a whirring pc a dream. I can actually concentrate !Couldn't be happier with the purchase, and although a bit more expensive, these will def last a long time.Highly recommended.

Very very good quality!

Omg, I am so impressed! I think Bequiet is the best!I have bought a Noctua and a Bequiet 140mm both. And i like the Bequiet more

Quiet and effective

This fan has 3 levels. The highest level is too loud for me so I don't use it but the 2 fans still keep the temperature of my 10-core 3-4 GHz CPU under 80°C under sustained full load. The non-pro version would have sufficed for me.

Noticeably More Quiey

High quality item - easy installation.

-10 degree difference

Was using standard 140mm's that came with case.. setting up a good fan curve and replacing with these resulted in a -8 -10 degree difference, very good.

Misleading

Decent but not what I asked for, I needed a fan same size as my stock fan and got one twice the size, it works decently but does the polar opposite of what it's said to do. By now my pc would've settled down but now it's rattling and sounds like a leaf blower while maintaining a consistent 74°c which is a improvement from the standard 80°c, I'm not happy it's loud even with the rubber washers placed on it not to mention reorganising the whole cooling system so I'd say this is the first and last time I buy this product from them again. I'm gonna continue trying to make it less loud and if I can't I'll just have to settle with the stock fan until I have a valid reason to install them in a newer pc..

Quality, but...

I bought them with the idea of hooking them up to a corsair h150i cpu cooler , But unfortunately they are not as good as they seem . cpu temperatures are practically the same as if I had standard fans from corsair

Be LOUD! Strikes Again!

I’ve had it with this company, it started with a power supply I had from them, a Dark Power 12 Platinum, noisiest power supply I’ve ever had!And now these, I thought I’d give them another chance, but I wish I hadn’t.Even at £5 a fan which I somehow got them for, they are absolutely horrible.By far the noisiest ‘silent’ fans I’ve ever had.I had 4 of these, and all 4 made really annoying grinding noises even at low RPM.They have “swappable corners” and “rubber fan mounts” to reduce noise and all this other pointless stuff that makes absolutely no difference, they are loud and a complete waste of money, do not buy them.Buy Noctua, Arctic or Razer instead.Avoid at all costs!
