COOLER MASTER R4-L4S-10AB-GP Blue LED Case Fan

Comment:
For the price ($7.15) these are decent. Grabbed one to augment the fans on a CM case. Not the greatest airflow or static pressue, and not the quietest, but it's adequate and the price point is good.

These things look great and are dead silent. I have 4 in my case along with 3 120mm ones. The only regret i have is that they dont move as much as air since they run slower. They are good for what they are though, you cant hear these things run. Just the slight sound of air. And I love the effect of having 6 of these blue LED fans shining outside. They are bright though, lights up the whole room. But I personally like the effect at night

i got this for my cooler master haf 932. wooks good quite bright blue. Highly Recommended

My only complaint is that this fan is clear rather than the dark smoke acrylic like the 120mm version.Other than that the fan is quite quiet and moves a respectable amount of air in through the front of my Coolermaster Elite 370.

I was surprised to find it's pretty quiet compared to the 120MM ones.

I got these fans to go with my Thermochill 140mm rad. I have three in a push and three in a pull configuration. I've hooked them up to a fan controller but they are pretty quiet. The LED's are quite bright so it would have been nice to be able to turn them off or a dimmer of some sort. I wouldn't say that the performance is extreme but using six in my application will work just fine.

I picked up a total of 3 of these for my CM690 II case (2 from 2 months ago and another last week). They match the stock 140mm that came with the case. Only difference is these are clear vs the stock one which are black.

I bought two of these for half price each what a deal. I put them in my Coolermaster 690 advanced case. Sweatness, will but these again, great product. If you need some good fans these are the ones to get.

I use two of these at the top of my CM 690 II to push the hot air out of the case. The model is the same as the one located at the front of the case, but without the feature to turn the LEDs off. Comes with 3-pin to 4-pin adapter. Overall a great product.

I ordered it because my Azza 910 didnt come with 2 infront fans. For some reason, mine isnt really blue. It has part that are teal.. Really wierd but i dont mind. Maybe a default of fabrication. I dont know... I dont think that i will buy this again. I will probably buy a fan that cost a little bit more next time.

Installed and running! Go figure its a fan!! LED's are really bright. I may cut two off and see if that cuts down on the need for sunglasses :-). Seriously they are bright. Material is flimsy but what can you expect for the money. It is truely a quiet fan. Moves a fair amount of air. Hope it lasts 3 to 5 years.

ive been using this as the main intake fan on my tower and its great. the color is a lot deeper than you usually see, sometimes it almost has a purple tint to it... if you dont mind paying a little more for a above-average fan, get this one.

It's a big fan, very bright, very silent, but just a little too big for what I'm looking for and it doesn't seem to do a thing! It's a very cheaply made fan, very thin plastic fins. Would not recommend.

Silent, effective and bright. Works outstanding.
