PC making strange noise.

There is a fan in the PSU, could it be that? If you can get at it and lube it as per my original post it may save you a few quid.

They are impregnated with white grease if you put oil or
WD40 its only a temporary fix, if however some white grease in a syringe
can be forced onto your shaft that will do the trick

If your cpu is a northwood then stock cooling, non-overclocked you should be looking at about 40C idle and 60C load. If it's a prescott then 45C idle and 65C load. I would say that 58C is a tad on the high side. A lot depends on the ambient temp, and the airflow through your case (which is a function of cleanliness, case design, number of fans and neatness of internal cables).

Having said that you have nothing to worry about at 58C. If you wanted you could probably knock 20C of that with a decent cpu heatsink/thermal paste/90mm fan combo e.g. Thermalright XP-90C/Arctic Silver 5/Panaflo.

I have no idea what the above means . Can you enlighten me please?

It's a prescott. I have three case fans (front, side and back) and I clean it regularly.

He's just saying that to drop your CPU temps down you could buy a new CPU Heatsink (the copper/alluminium thing mounted to the cpu with a fan on, which dissipates the warm air). Thermal paste sits between the Heatsink and the CPU and creates a much more conductive connection and therefore taking heat away from the CPU, into the heatsink to be blown away by the fans.

Thermaltake XP-90C: is a CPU heatsink
Arctic Silver 5: is a brand of thermal paste
Panaflo: is a brand of fans renowned for being quiet.

It would reduce your temps, but I'd concentrate on getting your PSU fixed beforehand if possible.

Strange noise didn't happen on start up today. I'll still replace the PSU though. I'll order one today.

Thanks for the replies

LOL.

I think what you might be getting is often referred to as coil noise, or choke vibrating. It's not from a fan, but the PSU itself. I can't remember the science behind it, but I've had the same problem (like a bee was stuck in there!). In fact mine (Hyper psu) used to make the noise even when the machine was off (but still on at the mains).

In the case of my PSU it was and still is fine after years of use. Some say though it's when the limits of the psu are being reached. Although my Hyper made that noise when the machine wasn't running, so I'm not so sure about that. Plus Tagan's were notorious for it, and people reported they definitely weren't reaching the limits on any of their rails. I think it's related to grounding, Tagan added a new cable to their psu's that links up to a motherboard screw which apparently helps.

Still, you may want to think about investing in a quality psu like Tagan, Enermax, or Seasonic (best IMHO although I have a Tagan).

A case is often a good way to go too. Better air flow will help all the components inside the case.

Something like the Antec Sonata II might be worth considering if you are thinking of a new PSU.

It's £78, is virtually silent, but still has very good airflow (2x 120mm or 92mm, I forget, fans). Great build quality and it comes with a decent 450W Antec PSU.

It is an expense though, a reasonable PSU will cost you nearer £50.

Note the above Tagan was on Aria a few weeks back for about £40. Worth keeping an eye out for.

what wattage should I be thinking of? (current one is 460, if I remember correctly). Should I be getting a bigger one? or the same?
