No, because the radiator should be hotter than the air its pushing through it and the whole point of pushing air is to extract the heat from the radiator.  Its not sticking around long enough to make a notable difference as its being pushed straight out the case.

What's the rest of the build?

 

Most likely it will use the pre-warmed air to cool the liquid. In general, fresh intake air through a radiator is better.

That depends, as in most cases that will heat up the GPU more which is what needs cooling the most.  Its always a compromise between shaving a few degrees off the CPU or the GPU, unless you have a case that can pull air directly from outside onto the GPU too.

Remember, air coolers have the same issue, they're sucking the hot air from inside the case, and they perform fine.  Unless you're doing primarily CPU driven tasks, I'd have the radiator on the top.

Generally fresh air is better . However its not the end of the world if its at top and draws hot air as long as u got good intake there shouldn't be any kind of problem

An AIO doesn't match regular gravity and so an AIO will push the liquid up and down. As far as cooling goes, depends on your case and such. But, having the AIO on the top of the case is generally considered the best option.

Generally speaking, having an AIO in your system will make the system run warmer. The AIO is dedicated to cooling the CPU or GPU, and gives no fux about the rest. So you plug up half your case with a rad to cool the cpu, and cut off or slow down a large portion of incoming or out going air. As for air coolers sucking warm air, that really depends on the fans you use, and your ambient temperature. I use an air cooler and my results are on par or better than an AIO, running a 12 core CPU..

That was exactly my point, traditional air cooling is identical to using a radiator on the exhaust - both are using the warm air already inside your case to cool the CPU, its absolutely fine and IMO how you should do it.

If that air is hot enough to cause a problem cooling your CPU, that's a flaw with your case airflow to begin with and putting it on the front would make that a whole lot worse as instead of impacting the CPU only, it would cause every component other than the CPU to run hotter, components which typically are much harder to cool in the first place.

I'm far less worried about my CPU running hot than my GPU, SSD, chipset, VRMs, etc.  If the CPU VRMs get too hot they will throttle the CPU anyway.

ducting air to the cpu tower cooler dose show an improvement same gos for the gpu

 

a good aio should cool better then the tower cooler because of it getting cooler air thow exhausting at the gpu is not ideal.

So should i put the aio on top of the case backwards or not

Top of the case, fans blowing through it out of the case.

Ok thanks

That's my recommendation at least for overall best cooling, if you're really curious then try different layouts.
