Problem in CPU Fan

[kg11sgbg]

@ Forum Friends, I am using my Desktop PC which is quite old,but it's functioning very well.

My CPU is an ancient Dual Core AMD Athlon64X2 4200+(Socket AM2;90nm soi;Windsor Core)

Problem is with the CPU Fan.
I had changed the default factory CPU cooler fan and attached a new CPU Cooler Fan by CoolerMaster model no :->DK9-7E52A-OL-GP
It was running very well for the past seven months or so,but now whenever I switch on the machine,all components spring to life,except the CPU Fan.
I had to manually rotate the fan(I am running my PC,with a side panel open for the past three months,here in Kolkata.The summer heat was unbearable a few days ago,but now despite of weak monsoon setting in at Kolkata.It's much cooler now.)to start it.
The fan seems to rotate slowly at first,but eventually speeds up after a few seconds.

What is the problem?
My interior of the PC is clean as I clean thoroughly with a brush and also use a blower.The CPU Fan is clean.

That CPU cooler is gone. If it is under warranty (most prolly 1 year from the date of purchase), RMA it. Otherwise buy a new CPU cooler.

Yup, RMA it if its in warranty. But why did you replace your stock fan?

^^Actually,the stock CPU Cooler Fan though running well is a headache to open and reset on the socket AM2+ of the motherboard,for cleaning and re-applying of fresh thermal paint.
In case of the Cooler Master CPU Cooler Fan purchased by me,the above action is just a breeze....

Correctly judged @d6bmg.

I reverted back to my old stock CPU cooler from AMD...functioning and running excellent.No anxiety,no more worries(for the time being...),no increase in Temp.

Don't underestimate AMD stock cooler. Its not as bad as you think.
