Title: Radeon HD 4800 squell / whining noise
Post by: blackmoor on January 17, 2014, 11:21:19 am
My cab has been making whining noise for about a month now. First I thought it is the display on itīs last legs. But today i disconnected the display and whining continued. I have new 12 cm fan on the radeon, disconnected it, still whining. And disconnected cpu fan, still whining :(

IS there any remedy for this type of situation?

Could be the power supply fan.  Stick a Q-tip in the back of the power supply fan grille so that the fan can't move and power it up for a few seconds to see if the whine comes back.  Make sure to pull it out after you've made your determination.   

If it's not the PSU fan, it could be a bad cap somewhere.  Are you getting any display weirdness when the machine is on, or issues with no video when you turn it on sometimes?

And I withdraw the quostion. Alas, it WAS the PSU. Itīs fan was jammed. it would not move at all. Changed new corsair 500 wat for it-> no more whining.

Thanx for all the help though :)

Glad you sorted it out.  That reminds me that I have to swap out my PSU fan (or PSU altogether) in my 3-player MAME cabinet someday soon.  I have access to tons of free parts due to my job, but have been too lazy to dig into it.
