hi guys some of you may be aware that the xtreamer fan can be quite noisy and in some cases can be very noisy. my xtreamer recently became stupidly noisy but i found a bit of wd40 solved the problem. be carfull if trying this, i took the entire fan out of the unit and allowed it to dry for a good half hour befor seeing if it worked. and hay presto its now as quiet as a mouse. i know you can get the passive cooling units now but im happy with the noise level now so may be worth a try for some of you.
