It may be that you PSU will overheat. It depends on the features of your PSU as to what the consequences of this are.
Some PSUs are equipped with a thermal cut-out in which case your PSU will simply turn itself off. Others will overheat, and internal damage to components will ensue, and your PSU and possibly your computer will cease to function (permanently). Your PSU may just catch fire in the worst case.
However, it may also be that your SMPS fan is thermally activated and only comes on when the PSU temperature is greater than some threshold; this is a design feature of the PSU if it is present. Some fans are equipped with a speed con troll that links the speed of the fan to temperature of the PSU. See you PSU details to determine which of the it may be. If it is a Zalman brand PSU, most likely it has a themally controlled fan. This feature also has propriety names such as "Silent Fan Technology" or "Whisper Fan"

Seems like its overheating. Check if fan is working properly. Plus give the fan assembly including the one in the SMPS a thorough cleaning with the help of a vacuum cleaner.

I am able to turn on cpu but the monitor is not displaying it. Power is coming, Two fans are running in C.P.U. Some times fans not work. Kindly suggest me why this happens and give the solution for it.


093aba5.jpgYou have a problem with your SMPS. Kindly send your SMPS to a repairing shop. If the guy suggests you to buy a new SMPS then there is hardly anything that u can do instead of buying a new one. I had the same problem once had to replace the SMPS as even after two repairs the SMPS wasn't working properly. There is a prob with the switching regulator for sure if your monitor works perfectly then.

I went and bought a new power supply today. because i noticed my power supply fan was not working. but my new power supply is not working nither


Sometimes this happens. A newly procured item also does not work. In order to check that your smps is working or not just unplug every output from it and give power supply to smps and check whether the fan is running or not. If not then smps is faulty.

Color Printer fan error


The SMPS Fan Error is caused by slow or no rotation of the SMPS Fan. The firmware solution from Samsung disables monitoring so if the fan stops the printer will keep working. Thankfully, it's not physically hard to fix this issue though and can be done by removing 9 screws and using a little oil.

I've actually posted a step by step guide to fix this here.
