definitely something is not right.
is this the case ever since you built your PC or it's something you experienced recently?
are you using an intel board as well? what model?
I am using intel DG33FBC motherboard.
I have done some changes in my pc case
Initally case cooling fans are blowing air outside at that time my Processor temprature is around 50 C. But there is problem that computer does not starts. neither fan nor hdd.
Hence i inverted those fans and now Processor temprature is 5-10 C.
But once it is start i donot have any problem and after 5 to 10min it shows Processor temprature around 20 C.
Is this normal??
My room temprature is around 30C since I am from mumbai
