HI, my coolermaster laptop cooler, the U2 with 2 optional fans have been acting loud. only one fan has been acting up. it makes loud noises while the other one is silent. like a grating noise kind of. cant really describe. please help. it also starts the moment i plug it in to my laptop. i bought this last month so i dotn know whats going on. there doesnt seem to be any dust blocking it. K.

Hi.

As Dean said, if the humming noise is always present even with the fan spinning at low RPM, replace it. If it's only loud when booting it might be normal ; some computer's BIOS spin the fan very fast when booting and when the Operating system or preset parameters take over, they gradually lower the speed. By the way, unplug the fans one at a time to find which one is causing the noise. If it is a case fan they cost only a few bucks, if it is the CPU fan it is a bit more expensive but aftermarket cooler can be found for around 20$. If you need to replace the CPU cooler, make sure you clean the old thermal paste and apply some fresh one. For a tutorial how Youtube is your best friends ;)

That laptop have no to much space to get the air , and when the cpu get hotter , the cooler starts to go faster and than he make noise to much , watch the cooler , take off the dust , and take care of the cpu .

check the fan near the motor or inside it this kind of wine cooler always have fan problem

i got the same model,the noise from the lower back,u can remove the fan out & determine the noise from easy,the bottom have two bolts,easy to remove it.gd luck for u

I believe the 6SBAR has an evaporator fan located behind the evaporator plate ( the cooling plate) inside the unit. They had some issues with the bearings in those fans failing and will sound like a small jet engine sometimes (high pitched whine). When you hear the noise, open the door and if the noise level changes (either gets louder or goes away) then it is the evaporator fan. If your noise is coming from the compressor area and does not change when you open the door, it is most likely the condenser fan blade is loose. The evaporator fan looks like a small computer cooling fan and is located near the bottom center of the evaporator plate (out of site). The factory sells a replacement kit with a much better fan and new power supply. You can reach them at 800-223-3900. Good-luck.

If the fan was not that noisy before , this can only be cause by a dirty fan and you may need to clean it up to reduce the hum coming out from it...

The problem is likely with one of the two fans. A new fan is available from Danby (1-800-263-2629). My noisy fan is the condensor fan located at the bottom rear of the device. After removing the cooler from under the cabinet, the source of the noise was obvious. You will need to tell them whether it is the upper fan or lower fan. Leave the cooler upright for a few hours before you plug it in so that you do not damage the condenser. Price for the fan from Danby is $20.15 including shipping.

when the fan comes on so does the compressor,hold the fan with a rag and see which one is making the noise-mike
