Corsair H60 can't mount as exhaust( help me with air flow question)

ubaa · May 12, 2016

I am building this PC, but I cannot mount the CPU cooler radiator and fan as exhaust because my back exhaust fan is only 92mm, it has to be 120mm. I have front and side fan slots that are 120mm, but they are in the front of the case and the side of the case. I am not sure how I should place the radiator and cooler. I don't want to be blowing hot air coming off my CPU on my GPU, or into my case from the front. What should I do? go with a different cooler?

Would it be a bad idea to put it in the front taking in air from the outside, and blowing hot CPU air inside my computer? Or have it sucking in air from the outside from the side?

Mounted in front as an intake generally provides the best CPU cooling performance, however, you do want to use this configuration only if you have sufficient exhaust cooling and optimally, other intakes as well. See this conversation that addresses this exact issue:

Further, what is your case model and how many fans, located where, do you have?

AIO water cooler fans should be mounted as intake so that cool air from outside the case is passed through the radiator. The temperature inside your PC is always warmer than the ambient temperature, so mounting the fan(s) as an exhaust will increase the temperature of the liquid and compromise cooling.

In some cases, exhaust configurations with AIO coolers is acceptable. Most often the temperature of the air inside the case is considerably cooler than the temperature of liquid that is entering the radiator, so you'll usually still result in an exchange of heat that leaves overall CPU temperatures within allowable specifications and thermal tolerance. It's still less efficient than being used in an intake configuration though, but without sufficient case airflow, a radiator in an intake configuration can impact the internal case temperatures enough to have some effect on other hardware so it's fairly important that there is sufficient exchange of airflow THROUGH the case, most especially concerning the exhaust configuration, in order to get that heat OUT of the case.

If you're not getting heated air out of the case as fast as you are putting it in there, via the exchange from the radiator, then a poor thermal condition might be created.

A 120mm single fan radiator as intake, with only a single 92mm exhaust fan, for example, would probably not be wise.

Thanks for getting back to me man. If you click "PC" in my original post, it will link you to all my parts.

I would not use any liquid cooling solution with the Core 1000 case. There is simply not a large enough location for exhaust, nor are there enough exhaust locations to make using the AIO as an intake a good idea. That case is for use with lower end components and and CPU air cooling. Further, the product page for that case specifically does NOT indicate component support for ANY kind of liquid cooling. Likely there is NO room for front mounting nor will rear mounting work. Mounting on the side panel MIGHT work, but would be a bad idea as you would be blowing hot air directly onto the GPU card and would still not be getting it out of the case fast enough with only a single 92mm exhaust fan.

I would highly recommend a more compatible case if you wish to use liquid cooling. Otherwise, you may need to sell or return that cooler and use a suitable CPU air cooler along with case fans in all the available case fan locations.
