Can push/pull INCREASE temperatures over just push?

[Internet Swag]

Example

 

Stock Hyper 212 Evo comes with one fan.

 

You add a crappy 120 mm led fan as pull. 

 

can the 120mm coolermaster fan actually push air so much that the 120mm led crapfan cannot pull it out fast enough causing a temp increase?

 

Or will push/pull always be superior to just push?

Yes Push-Pull will be superior by 2-3 Degrees... while also increasing noise and taking up more space.

many factors will affect your temps,

 

1. mass flow rate through the cooler

2. fan situated lower down on the cooler close to the base

3. static air pockets

 

so yes push pull will help with the mass flow rate through the cooler. 

 

i run my h212 in push pull, temps are as previous poster mentioned about 2-4 deg lower than single fan,

you can also use 140 mm fans on the 212.

Push/pull is superior by a few degrees which is negligible. As far as I know, what you stated won't happen. Push/pull is just louder and takes up more space. Generally you only need one fan in push per CPU cooler heatsink, for example on the NH-D15 that Noctua makes, you won't benefit from adding a third fan at the back of the 2nd heatsink in pull.

Main reason for going from push to push-pull is reducing fan speed and so noise.
