As we are already aware that the RTX series GPU’s from Nvidia is already announced and is currently available for pre-order also and on the other hand we also came to know that AMD’s next-gen 7nm will also be getting released later this year. We have already seen some manufacturers reference model design for the RTX series GPU’s. Now if you are going to buy a new GPU, you must be aware of certain facts such as the length of GPU, the heat spreader or the type of cooling it is offering. What will be discussing today is the details about the types of cooling and their way of working.
There are basically two types of cooling solution one being an open-air cooler and on the other hand a blower cooler. There is one another type of cooling solution trending these days and it is the liquid cooling solution. But we will skip that as most of us don’t want to go with that build except for enthusiast and I guess most of us would agree with the risk factor involved with that kind of build. I am not saying that it a bad choice to go for a custom liquid cooling solution with your GPU, all I am saying is that one will need to be extra careful about installing those types of equipment as well as maintaining them. However, there are certain GPU’s that offers AIO Liquid Cooling solution but again you have to consider certain things before buying one which includes the PC case one has as it should have an option for mounting the rad that came along with the GPU itself.
Now between the Blower and Open-air cooler, one should first understand on how they actually work. Their purpose is to clear away the hot air from the GPU with the help of a heatsink and a fan. It is quite similar to that of the functioning of a PC case fan where the Intake fans bring the cool air and the exhaust ones blow out the hot air from inside of your case. However, in the case of GPU’s they act a little differently, both of the types use one or more fans along with a heatsink to take in the hot air from the inside of your case but they don’t blow them into the air immediately. Instead, an open-air GPU takes in the hot air with the help of the fans and then they are spread all over the heatsink and then the air was expelled back inside the case through the openings and the reason why they are known as open-air as there is no obstacle between the heat-sink and the air inside the case and a picture (below) might make it simple to understand where the blue arrows represent the fans which bring cool air and the red one represent the hot air which is blown away in the case.
On the other hand, the GPU with blower design comes with an extended protective plastic all around the heat-sink and the only opening area it got to blow those air out is the opening near the IO of the card. The fan in this design takes in the air from inside the case exhaust it out completely through the ventilated openings of the card out of your case. The picture below demonstrates how it works where the blue arrows indicate intake and the red ones indicate exhaust.

Now the main question arises about which one is better for your build and in this case, I will try to keep things simple as much as I can. If you have a case which has nice airflow along with lots of space for the movement of air inside of your case then the best choice for you will be the one with open-air cooling. On the other hand, if your case has less room to breathe and along with that you are going for liquid cooling for your other components then the best choice is the blower type card as it will simply exhaust the hot air outside of your case. But the variation between these two type of cards are minimal but depending on the surrounding environment and your other hardware components you will need to make your choices.
