Does air heat up significantly after passing through a rad? - Page 2

post #11 of 35
There is no such thing as too much CFM on a radiator. All you need is adequate CFM to blow out the heat being radiated.

Yes. Almost as hot as your water.

Yeah, I realize how hot the air gets would depend on what setup and load the rad is cooling but just wanted a general answer.

Yes, depending on how many watts you are cooling it can be many degrees C hotter.

thats why people who put rads on their intake fans are pretty much heating their components back up and mostly the one that suffers are the GPU and chipset (SB and NB).

Thats why I don't get people using radiator on front (intake) panel and saying it doesn't heat up the system, one person tried to even argue with me and when he tested his NB temps went down by 6C under load when his radiator was set at exhaust not on intake.

but that doesn't mean you cant put rads on intake, if you got no where to place the rad except the intake slot, then no choice but to do it there, but try to avoid putting rad on intake slots.

I described it as, "hot air" because that's how you described it and I wanted to be sure you knew which "air" I was asking about.

I don't think you've understood my question correctly m8:p

This is actually exactly why I was asking this. I just got a 500r which will be used with my currentt sig system, didn't have a case lol, but I'm planning to use it next year after I've saved up to replace everything - and was looking into ways to make it work for water cooling. I got it for $90 so pretty good deal, and I really, really like the 500r in terms of aesthetics. So anyway, the plan was to cut everything out in the front and have a triple rad in the front with a slim dual rad in the top. There is a user who posted his rig in the carbide series club thread where he does this and it looks very nice. It inspired me to make it work with this case lol.

The 500r does have a bottom fan mount, and the side panels that could bring in some fresh air. I was hoping I wouldn't have to use them because I wanted to mod in a black plexiglass window, maybe the bottom one alone will be enough, or maybe I won't even need it, probably depends if I dual graphics cards or not... okay getting off topic.

Unfortunately there is no magic solution if you want to mount the radiator in the case. If you put a radiator on the intake then it maximises cooling for the radiator (and whatever it is connected to) but vents hot air into the case. But if you put a radiator on the outlet then you are using hotter air to cool the radiator. The difference will typically only be a few degrees, but it comes down to which systems are a priority to cool.

The only way to get around this is to mount the radiator outside the case so that both intake and outlet are outside the case.

A good custom loop will blow air that is maybe 5°C hotter than ambient. The better your loop is the cooler the air will be.
