i would agree with the previous posters, kung pinalitan lang yung mga carbon brush nyan, sandali lang ang buhay nyan.

i also do not recommend using surplus fans. you will never know when it will die on you.

replace it with a replacement part. to give you an idea, my aux fan also died around three weeks ago. i had it replaced with a brand new replacement part at Ceejays (too). Costs 4,500.00 compared to the OEM which costs Php 6,500.00. The replacement motor comes with a six month warranty with Ceejays too so walang magiging problema. May peace of mind ka pa.

Mahirap magoverheat ngayon lalo na summer.
