Conure Posted June 13, 2011 Posted June 13, 2011 Hey guys, Having a weird issue. As of this morning my PC (PSU I am 99% sure) has been imitting a strange high pitched whine. I thought it may be the fan to stopped each fan independently and it's still doing it. I've noticed the whine changes pitch when I open internet browsers, stress the CPU etc...It also fluctuates in pitch...I presume this is sounding the end of my PSUs 3 year life.....Odd as it's a 700Watt PSU and has never been particularly stressed... Anyway, I'm hoping it holds out for 2 weeks so I can get an entirely new case and PSU. Is there a way to diagnose if this will damage my components? Anyone had this issue before?

Conure Posted June 13, 2011 Author Posted June 13, 2011 Cheers for the reply Sobek :) I pulled the rig apart and ran it with just the PSU - it's definitely the part making the noise. If I posted voltages etc would you be able to tell me if it's healthy, or should I take it to a hardware forum?

Rahvin Posted June 13, 2011 Posted June 13, 2011 You will probably have to measure the output with an oscilloscope and artificial loads to check the ripple values. Those are often linked to noise and also more likely to lead to problems in other devices. The problem is, that measuring that will most likely be way more expensive than a new PSU. If the whine annoys you, try and get a new one (Seasonic or Enermax 450~500W) and see if it goes away. In my experience, having a surplus PSU is always a good thing, as they don't go out of date, and they are one of the components that are the most likely to break during a computer's life span. 1
Haggart Posted June 13, 2011 Posted June 13, 2011 In my opinion, it sound's a bit like leaking capacitators, where the capacitator liquid reacts with the oxygen - had that in a PSU of an external RAID-drive some time ago, took me some time to find the failure 'cause the voltages kept kinda stable - but if it's that, it's possible that your PSU will die soon. But - if it dies because of that, it's unlikely it damages anything else :) Is it more like a whine or more like a high flowing sound (like someone who whistles very, very high and soft)? 1 There's no "Overkill".

Conure Posted June 13, 2011 Author Posted June 13, 2011 Hey guys, cheers for the help! Bought a new PSU....Also ordered some fans, though I've got no fan ports...Am pretty much going to have to glue them in.................

Well, the problem is that electronic parts do age (especially capacitors), faster if they are in use but they still age if they are not in use. E.g., you can't expect a surplus PSU that has been laying around for 10 years unused to last as long as a newly bought one. Good, fast, cheap. Choose any two. Come let's eat grandpa!

EtherealN Posted June 14, 2011 Posted June 14, 2011 In my opinion, it sound's a bit like leaking capacitators, where the capacitator liquid reacts with the oxygen Either that or coil whine, which is more benign (though still frustrating). Old CRT TV's were prone to this under certain conditions. (Basically a resonance with the frequency of the current passing through the coils). I do however not recommend the "trick" that used to work for CRT TV's - banging them hard. :P [sIGPIC][/sIGPIC] Daniel "EtherealN" Agorander | Даниэль "эфирныйн" Агорандер Intel i7 2600K @ 4.4GHz, ASUS Sabertooth P67, 8GB Corsair Vengeance @ 1600MHz, ASUS GTX 560Ti DirectCU II 1GB, Samsung 830series 512GB SSD, Corsair AX850w, two BENQ screens and TM HOTAS Warthog DCS: A-10C Warthog FAQ | DCS: P-51D FAQ | Remember to read the Forum Rules | | | Life of a Game Tester

(Basically a resonance with the frequency of the current passing through the coils). IMHO kinda unlikely, since the transformer in a SMPS operates with frequencies well above 20kHz (that's why it can be made so small). It is more likely that some filter capacitor has aged, letting some ripple through, which can be audible. In any case, proper diagnose would necessitate knowing the intricacies of the PSU design in question, which is quite an assignment given todays PSUs complexity. I'd just send it back to the manufacturer, if warranty is still provided. Good, fast, cheap. Choose any two. Come let's eat grandpa! Use punctuation, save lives!

Conure Posted June 14, 2011 Author Posted June 14, 2011 Hey guys - thought things went well but they didnt! Got some more fans in the PC and they are awfully loud, i can deal with that..I swapped my cpu fan for a new one as the old one could only have one slot of ram...Now, with PRime 95 and no overclock the CPU is getting 76oC...Seems crazily hot...It seems to be mounted correctly. I think I need a new MOBO so i can fit a decent CPU fan on there. Can anyone recommend a nice spatious motherboard that doesnt have ram slots within an inch of the CPU?

Conure Posted June 14, 2011 Author Posted June 14, 2011 Hey all, final question I promise. this is bothering me! Basically I switched out my old CPU heatsink which was considerably larger than this one. With the old one I couldnt fit all my ram in, with this one I can. I also have added 2 new fans to the case, so airflow is much better, but this is what's weird. During games (eg the witcher 2, and DCS A10) my CPU and video card are very very cool, cooler than before....Yet on benchmarking (furmark and prime95) their temperature is crazy. For example my CPU hit 76oC after half an hour of Prime95 - thats a crazy temp for a stock I5 isnt it?? Is this something to worry about, or should I just relax? No game has taken my CPU above 60oC, but the Prime95 temp has me concerned...

So I think its a great trick :lol:

Why, do you make a habit out of running prime95 to heat your flat? :) Seriously, those programs use algorithms that are designed to max your CPU out as much as possible, much more than a game can. AFAIK with 60°C you are still in the green. Edit: On second thought: when you say stock, do you mean stock freq? That would indeed be just a bit high. Did you use quality thermal paste and is the cooler fastened to the CPU properly? Edited June 14, 2011 by sobek Good, fast, cheap. Choose any two. Come let's eat grandpa! Use punctuation, save lives!

Did you use quality thermal paste and is the cooler fastened to the CPU properly? Hey there, It's not a stock fan but it's roughly the same size, using crappy pre applied paste. I'm sure it's attached properly though as I took the motherboard out to attach it. With my old HSF it wouldnt go above 51oC so it's a huge huge jump. I think to be honest I need to buy a new motherboard which has the space to equip a decent HSF. Still, if it's staying below about 55 on games that suggests its not going to cause damage I think?

Conure Posted June 14, 2011 Author Posted June 14, 2011 Cheers Sobek :) I just ran the test again and um...The temps are down by 10oC....Maybe that stuff I've read about thermal paste taking a few hours to work properly is true........
