yes, I could easily cut them with a plier, as they are small size & much thinner in my case. God rid of the noise.
Even if u do not have four holes , there is one practical idea. cut ribs at 3 points , as marked blue in yellow circles. Leave bottom point uncut as shown in green rectangle), Band the green point to downward ,lubricate fan , rebend the strip back again in original place. I did it successfully today & noise stopped. Also, grill remained intact except having 3 cuts...!!!!!! to maintain vermin proof-ness function.
