Neponyatki with PD
power supply Thermaltake Toughpower 650W (W0104) were purchased in the distant 2010, and now, after 7 years, just started to buzz, and the valve spins to the limit, the temperature at the exit of BP from 40 to 44 degrees under load, could it be that after time it loses power. Drove SCR test power supply on the +12V line drawdown go to 11,660 in that screen, when measuring with a multimeter in idle the voltage jumps 12,08-12,14, under load in 3DMark 11 12,14-12,18 in, shoveled a heap of forums, everywhere write that software monitoring can not be trusted, what about the reading on the DMM.

Over time the PSU can actually lose power due to aging components. But your BP is too strong voltage deviation from the norm. Allowable deviation is + -5% from the norm, the greater the deviation significantly harm the components of the PC. Monitoring does not always give the correct information. You can still use the BIOS to check the voltages the PSU or the program SpeedFan.
About of buzz, strong promotion, high temperature: the fan requires lubrication, high temperature may be due to the warm air in the house or, worse, huge amounts of dust inside the PSU.
Yet, by the way, there are some symptoms? Something like high frequency squeak that can be heard inside, a sudden restart of the computer, long power on, long off, the voltage at the system unit???
Cheep \, sudden reboots or anything and there was not, the PSU is clean, THEN every two months, the case I have a zalman z9 3u air intake of the PSU on the bottom, and again, a multimeter checked the voltage in idle 12,08-12,14 In under load it on the contrary rises and falls and it shows the drawdown as the screen, well the valve I removed, although I think replace with something like current that was quieter. The voltage on the case of ka it can be, supposedly breaks somewhere?

Well, if BP, clean inside, no broken parts, just change the fan, he is buzzing for a reason, and due to the lack of lubrication or worn bearing. Fan change, and subsidence do not pay attention, unless they are below 11.6 and 12.7 more. The voltage of the system block is always there, but at BP it is felt stronger, Yes, maybe, somewhere breaks.
What is the valve take, they are all with 3 or 4 pin and two pin PSU is needed if it to MP connect the connector under where the fan is, will it work if the PSU is not connected fan.
