cpu heatsink fan making noise even though i dusted

[sioni90reggae27]

I recently been experiencing noise coming the front fan of my Cpu fans.
Even though I dusted the dust behind the fan the sound still persists...
I restart my pc and it goes away but before I cleaned it wouldnt go away...
I feel the dust only fixed some of the problem... Could my fans be dying?
The only way I could kill the noise is if I stick my finger and skip the fan...
I removed the dust bunny behind the 1st fan and used a toothbrush to brush it...
its not clogged it just had a bit of dust on the cpu cooler

Should I buy a new cooler? What do you suggest?

what does the fan sound like? a fly buzz? a grindy whirl? an electrical whine?

fly buzz is caused by fan blades rubbing agianst housing

grindy whirl and electrical whine may point to coils or bearing wear. if you can use your finger to push the fan blade 'past' a sticky point to resolve the noise issue = bearing wear.

get new fan

i use a h60 liquid cooler for my i7 6800k oc'd to the boost by default.

i know its the smallest, keeps the cpu at 36-40. i saw amazon got a blackfriday deal for a h80 but im not fiddling with something not broken.
