Aspire V3-772G Odd fan noise after cleaning

Let's start off with:

Acer Aspire V3-772G (Intel(R) ore(TM) i7-4702MQ CPU @2.20GHz, 8 gb Ram)

 

Regardless:

After noticing a slight dip in preformance from games and use of my laptop in general so i decided to clean the fans. As this laptop is close to impossible to open up i decided to clean it the easy way, to blast compressed air directly into the fan in slow and infrequent blasts. After getting alot of dust out of the system i turned the laptop back on only to hear this "cd-reading"-like hissing from the left side of the laptop (where the fan is). Being worried i might have broken something i turned it stright off, and then on again realising there was not much i could do about it right now.

 

I am worried i might have spun the fan to fast, causing this, as the fan did not make this sound when i bought it new or before i cleaned it for that sake. It was bought online from a norwegian store (i currently live in norway) at 2014-08-18.

I thought i would ask here before i contacted the store or support to see if this is just me over-reacting or if there is a genuine problem. So is this abnormal, or just normal since the dust just recently got cleaned off?

 

Thank for reading my message, and i look forward to replies from you guys.

    I've blown out many laptops and spun the fans very fast and never hurt one.I usually just blast then good. You might have dislodged something that didn't blow out and is rubbing on the fan.

    Thanks for this insight. I am not really that into the physical of a computer so i was worried i did permanent damage to my laptop. After letting it sit for a while the sound started to come rarer and rarer until it stopped completly, which supports your claim. Thanks!
