Question DeepCool LT520 - One fan slower than other, making noise until pressed

[MarkB94]

I've been using a DeepCool LT520 for about a year. A few days ago my computer started making a loud rumbling sound. After opening the side panel, I noticed one of the radiator fans was running very slowly.

I tried restarting the PC but it continued to be a problem from start up. While the computer was running, I put some pressure on the center part of the fan with my finger to stop it and check if there was any wires touching off it and when I let go it went back to full speed and stopped making the noise. After a few hours it started making the noise again and I'm able to get it to stop by slowing the fan with my finger.

Out of fear that this will get worse, I thought I'd kindly ask here if there could be a more permanent solution to this problem or if I might be able to just replace the fan and not the whole cooler. If anyone here has some advice for this problem, it would be much appreciated.

The fan's bearings are probably on their way out. Change the fan, Shouldn't be too expensive.

Just before finding a replacement fan, try to find out the WARRANTY for this unit. A fan ought to last a lot more than one year, but I could not find actual warranty details on their product web page.
