My CPU temps did a jump almost over night. One day they were 33-35C idle and 45-47C under load and now they are 46-47C idle and 52-55C under load. How can this sudden a change happen and is it anything I should be worried about?

The CPU is a AMD Athlon 64 X2 4400+ and the mobo is a ASUS A8N-SLI Deluxe.

Hi,

It is difficult to say why the change. Have you checked to see if any fans have died inside the case (all types including heatsink, video card, case fans, motherboard, etc), or maybe even have enough dust in them that they have slowed down considerably or not functioning properly. That should be the first thing you need to look at.

About the temps, the second temps while rather high are not threatening. I would not worry too much unless your stress temps get to over 63c, and at that time, I would be very concerned.

When I start the computer there is a short ratatata, like one of the fans were hitting something but opening the case I didn't manage to figure out what it was.

Also, when the CPU temp goes above 50C the fanns start spinnging way faster and the sound volume goes up something like 10-15 dB, which is a bit distracting.

Hi,

They start spinning fast because the unit is too hot and that is what it is supposed to do. The key here, is too hot.

If you don't find the fan that is hanging, then you need to take the unit out of the case, set it on a piece of cardboard or a non-conductive surface and find what is going wrong when you fire it up and can see everything. You don't have to put everything in to see or hear what it is out of the case.. You MUST get that fan noise solved before you go any further. There is a reason for that, so you need to find it.

I figured out what the ratatata sound was. It was comming from a frontpanel audio connector that I don't know what to do with. It was hitting the fan, but would be blown away from the fan after the fan started to spin fully.

Another thing I noticed was that whenever the computer boots up through it 10 min long bootup process it would stop for about 1 min at this message: IDE 0 channel 80 no connductor cable connected. After sitting at that message it would then continue boot up.

Hi,

The long boot up is probably because you don't have an 80 connector cable hooked up. YOu probably have an old 40 connector. Would guess if you put a new cable on there, your rig will work O.K. That would be a cheap solution.

That's kinda strange, since I'm using the IDE cables that came with the motherboard.

And I did a defragment, now the boot time is just 6-7 min. :grin:

@ Mr Alpha
I see that most motherboards come with 1 or 2 80-conductor cables and 1 40-conductor cable. The 80-conductors cables are for the HDDs and the 40-conductor cable is for any Optical Disc Drives you may have(dvd-rws etc.). Are you using the 80-conductor cable? You can probably count(by feel with your fingernail) to see how many conductors the cable has..you should be able to tell by counting halfway across. Also if you can easily distinguish between wires on the ribbon, it is probably a 40-wire cable as each wire on 80-conductor cables are much harder to count as there are twice as many. Also a 40-conductor cable has the same cable spacing as a floppy-drive cable, if you have one or are using one to compare with.
