"Mainboard temperature" too high?

I'm using hmonitor and it says my "mainboard temperature" is at 54.0 C and my CPU1 temperature is at 75.0C. However, I'm a bit confused, is this too high or what?

The reason I'm asking is lately my fan has been really loud and my computer has been going really slow, unless I restart it or leave it off for awhile.

Any suggestions, maybe too much dust caught in the fan or something? And is there a correlation between the temp and my problems?

 

Those temps will cause problems they are both 20 degrees too high,clean out any dust and check to make sure all the fans are spinning,have you had the heating on for winter? Both a high mobo and cpu temp are symptoms of poor case airflow and\or high external ambient temperature

 

Thanks, it's probably the dust then or something.

 

Dust wont cause 20c spike in temp, poor thermal aplication, fans not working, or something obstructing the airflow is causing such spikage.

 

Could be a poorly ventilated case.

 

As OM said just dust wont cause such high temps I should have posted this before you need to check the temps are for real run these progs to see if the temps match

I've had this same case for 3 years and never have ahd a temperature problem. And the programs are constant with the high temperatures.

I've cleaned out dust which have dropped the temperatures significantly. Also, my computer isn't freezing up anymore, but the temperatures still spike sometimes. Is it possible that the fan isn't operating properly? I know it's spinning, although I'm not sure if that's good enough.

 

Could be that or it could be that there is poor contact between the heat sink and the core.

 

There are quite a few fans in a computer you need to check they are all spinning,check inside the power supply to make sure that fan is spinning 'the box usually at the top rear oif the computer',have you had the side off the case to check all the other fans,poor contact with the heatsink doesnt explain the high system temps,the only thing I would be looking at,at this point are system fans.

1.Make sure they are working,make sure they are drawing in and blowing air out as they should ie they are spinning\installed correctly bottom fans intakes,top fans extractors,front fans intakes,rear fans extractors

2.make sure there is lots of clearance around the outside of the computer,move it out of the corner of the room if thats its situatioin and also check the the temperature of the room your in,warm ambient air has an accumulative effect when passed through a computer,turn your heating down do your temp probs have any correlation with the first time you turned the heating on for winter,is there a radiator behind the computer?
