Hi
I have a hot spot somewhere in my PC. Almost certainly on the MB. What started me wondering is a serious hot electronics smell that happened any time CPU use rose above idle. Watching a HD movie it is noticeable across the room. I fear damage. It also makes my eyes water. so far I have:
1- replaced my not so good power supply with an 850W Seventeam to see if it was the cause. No change.
2- got Speedfan 4.40 and spent a week calibrating it. I have found that my CPU,hard drives and cores are all well within tolerances as are the temp2 and temp 3 which I am thinking are the ambient and the remote ambient. I got this by comparing Bios readings with speedfan. Not certain though. Speedfan shows a Temp 4 that is very high. and that rises pretty fast with any CPU use and coincides with the burning smell. It does rise and fall with use and at one time it was getting above 70/80c. Since it changes I don't think that it is a false reading.
3- After 2 I cleaned the case carefully, removing the fans and really cleaning. I discovered that one of my case fans was in backwards (whoops) and fixed that. I did see an improvement.
4-I replaced all e case fans with new Noctua fans(wow they are unbelievably quiet!) and got some more improvement in the temp 4 reading.
This is where I am now.Temp 4 can go tp 65c at 100% CPU use. It is not associated with Video, it goes up regardless of weather I load it with Video or Antivirus scans. I am running a HD video now that uses 9% CPU and temp 4 is 53c but I suspect that the real hot spot is hotter than that because of the smell which I am getting now. Although my CPU fan changes speed according to load the other three seem to be oblivious to the heating. Performance is never affected. I have some improvement but I need more.
I need to
A- Find out where Temp 4 resides and therefore where the heat is so that if necessary I can direct air at that point and
B- Get all the cooling fans to run at speed when needed. Right now Fan2 (wich is plugged into the aux header does spool up. I have tried to get Speedfan set to increase the speed on more than one fan when temp 4 rises but I must be missing something!
Any suggestions would be appreciated on either fan speed or location. Sorry for the long post but I thought the info would be necessary.
