Hyper 212 Evo Fan Wrong Side and Thermal Paste Over Flow

[NuclearArrow]

I built my first PC a few days ago and i realised now that the fan on the heat sink is blowing air towards the ram side and the exhaust fan blowing outwards therefore both fans not getting enough air, how much of a problem is this because i can't pull the fan off as it is quite tight and the heat sink jiggles when i try and pull the fan off. Also when i applied the thermal paste it was a bit runny and now i notice that a bit of flowed out and is visible if you look closely enough.

What paste did you use , shouldn't be thin or runny.

You only need a pea sized dot in the middle , shouldn't overflow.

I used the defualt paste that came with the cooler and only tried to use a small amount but more came out and didnt seem that thick to me.

I also just stress tested the cpu for 2 minutes using prime95 and these were the temps.

At idle the temps are around 27 degrees celsius.
