You should clean out your case, I have had alot of problems like this where there is alot of dust in air cooled pc's. If there's alot of wires hanging inside try using cable tie's to tidy up any loose wires. If none of this helps think about where you have your pc. When I had this problem all i did was move my pc and all temps lowered by 10 degree's. Hope this helps
as for the cpu temp meter use this >>>>
