Bgearsb-Blaster 70 mm 2 Ball Bearing 4500 RPM DC Fan with Excellent Airflow upto 48 CFM - Black

Fans are more noisy than the description, They moove some air can not complai about that but the problem is that the seller limited to 3 PKS for buyer i dont know why but i have payed for the Bgears b-Blaster 90 x 38 mm 2 Ball Bearing 4500 RPM DC Fan JUST £ 5.76 FOR ONE so maybe that is the reason the seler limits the number of fans you can uy so he can sell them double the price after a couple of days SO the increase of price decreased the stars from my review and it deserves just 1 starr for the fan as quality is not worth the curent price, is too noisy.

I love the fans yes they are noisy but for mining they keep my rigs cool only problem is the price.... Why does it fluctuate so much? I've paid£ 5.99 for the 90mm then next time it's £19.99 ridiculous pricing and you are limited to 3... Why? Surely you want to sell as many as possible? Anyway get the prices set at a reasonable rate and don't put a limit I would give 5 stars

Used these on sim rig for wind simulation. Not strong enough on their own. But with a air straightening nozzle on front work surprisingly well. Moderately Noisy at full speed, but expected when moving a lot of air.

First the description looked like 2 fans very annoyed I received only one, description is misleading.I quote.."Bgears b-Blaster 50 mm 2 Ball Bearing 5000 RPM DC Fan with Excellent Airflow upto 17 CFM "The fan arrived and it's making loud ticking sounds at low speeds and is very noisy at high speeds.No way can you get the fan to operate under 40db at low or high speeds.

this fan may have a high air flow but you surely pay for it in Decibells

Bought these to pull/push air in several 200x200x80mm cases I have. Very noisy on first install but by using fan tuning software e.g Asrock"Fantastic tuning", Gigabyte "S.I.V" you can get fan speeds/noise to acceptable levels

They are a bit noisy, but that's to be expected for such high speeds.Made a custom cooling pad with 3 of these, 970m with 25% overclock runs at 65° vs throttling at 92° without.Great value.

It's like an aircraft taking off way to loud for any application.
