GPU temp increase after adding bottom intake

[sacred789]

Hi guys, like topic suggests. After i added a 120mm intake fan on the bottom of my case, blowing directly to my nvidia gtx 780ti, my GPU temp increase by 3 degrees under full load.

 

Many I know how come?

you sure you put it in as an intake?

Are a lot of your fans intake fans?

Try and have the same amount of intake fans as exhaust fans.

 

If your gpu is not using a reference cooler (blower style) than you may want an exhaust fan where the gpus are situated.

Otherwise the hot air stays inside the case.

Does the video card intake or exhaust from the fan(s) on it? You might be messing up the airflow if you're pushing intake at the card and it tries to exhaust into the intake fan.

My graphics card is a reference gtx 780ti, with the 80mm intake fan.

The 120mm intake fan that I installed is directly under the 80mm fan

try putting it in as an exhaust, really you just have to see what configuration of fans keep the best temps. Sometimes it's the weirdest configurations that keep the best temps.

Has your case good clearance under it? And do you have dust filter with that bottom fan? 3deg raise is quite minimal and I wouldn't worry over it.

There's around 1cm between the bottom fan and the case rubber feets. And yes there's a dust filter with the fan.

Problem is, my gpu went from 82deg to 86deg full load.

Those are pretty high temps over all. I thought reference cooler could do better. There's change that bottom fan and GPU cooler are so close to each other that airflow from bottom fan is interfearing with GPU's cooler. So if you have spot on side panel for fan you could try that instead.
