Since purchasing this computer I have been assaulted with the fluctuating, whining, high pitched emanating, whistling fan from a dimension of pure torment.
This fan will start to whine if the CPU usage goes over 20 to 50 % but it would appear only if the cpu usage drops down lower again (this of course being an extremely common occurrence with computers). So for example if the cpu usage is at max 100% consistently then the fan wont whine, but if it drops down or fluctuates to a lower percentage then the fan will emit this extremely irritating high pitched whine. Also interesting to note is that while at 100% the fan does not noticeably speed up by any degree only revving up for a second when not of any real use.
I have had the motherboard replaced which did help ( in the sense that the original motherboard had the fan whining persistently even under 0% cpu usage) but has not in any way solved the problem.
I have had 2 fan replacements, a heat sink replacement and after my computer being in a service depot for 2 weeks they only replaced a hard drive which had nothing wrong with it (I had previously tested the drives) and sent the whining thing back to me not repaired. also have tried using artic silver 5 thermal paste, no use.
I can not find a solution to this and I may seem that dell don’t know what it is either, to be honest I may think that it is a badly engineered motherboard, especially in conjunction with that worthless smart fan technology, bad move.
Anyone else have any idea in what direction I should look for this problems origin, im getting kind of sick of the service calls and changing the fan.
Sounds just like my situation! I had the fan replaced to no avail. I tried to get Dell to replace the heat sink, but Dell India solution was replace the PC which is not an option as I use it for work. I was transferd to a Dell tech in TX and he pretty much said "that's they way it is !" I was told they're working on a new BIOS, but who knows if the fan issue is being addressed.
The frustraiting thing is hearing of people with 8400 with no noise issues, even under stress!
the overall noise that the fan makes is not really a problem for me, its these really muffled very audable whistles coming from fan in cycles.
i have toyed with getting a new fan but there are 3 problems with doing this for me.
1. putting it into the shroud casing without damaging the rubber grommets
2.dell motherboard has 4 pin fan connector, will cause fan failer message with new fan
3.cant find any fans with the depth of the installed fan.
if i scoll up and down a web page quickley and then stop , the fan will burst into speed for a second causing a very irritating whistle, very audable. cause this increases cpu usage for a second.
this happens so often its driving me nuts.
