New to water cooling, need some pointers on getting started.

Over the years I've seen tons of debate on this. The bottom line ultimately is that it does not matter. Your loop will settle at a temp and will generally not fluctuate much as it flows between the CPU and GPU.
 
The only set in stone rule is that the reservoir must feed the pump without interruption (i.e. no components between them). Utilizing a res/pump combo eliminates the possibility of error here.
 
I've seen a slight decrease in CPU temps when I go to the CPU first and than the GPU since the CPU is more sensitive.

Do people always use reservoir's now? Back in the day we had T lines for drain and fill...

It's much better to use a reservoir so it catches all the air pockets, let alone easier to fill and less worries of spills.
 

I run the opposite of what your drawing shows the rad exhausts out of the case and the top and rear are intakes, that way you are actually supplying a solid air flow to the VRs around your CPU socket, which will allow your M/B to run cooler. Motherboards are still designed with the traditional setup of the VRs surrounding the CPU socket which was supposed to be cooled by the stock air cooler. But today many CPUs are coming without stock air coolers and many are choosing the AIO setup, but never replacing the air flow the motherboard actually needs around the socket. Which forces the M/B to run hotter and shortens the lifespan of the motherboard.


When it comes to the initial installing of the O-ring G 1/4 fittings to your radiator, water blocks, and reservoir, most instructions tell you to install them finger tight, I always go finger tight plus and extra 1/4 turn tighter using a wrench, if you don't it will eventually back off from expansion and contraction. The ring that forces compression on the tubing itself you do install finger tight and check occasionally to make sure it stays finger tight.

Well, you could go with that configuration but if you're worried about dust being caked on your stuff, you'll want front/bottom intake and top/rear as exhaust, assuming those intake areas are filtered plus you'll be feeding your rad with fresher air instantaneously.

Also, flipping the front rad so the ins/outs are at the top so any air pockets can exit that rad and eventually make their way to the reservoir would be recommended.
 
thats a good point. the front/bottom/side fans usually have filters but the top and rear usually dont.
 
well i see one problem .. the GPU blows heat to the back and the PSU. The back fan has no filter because its blowing out with the GPU and PSU.

Standard airflow is top/front intake as that's where the filters are usually and top/rear exhaust. If there's a filter at the top, turn it to intake as well since it'll be fighting against the filter and circulating that airflow up there. Everything else usually exhausts out the back via positive pressure.

Generally you are correct but in this application the GPU is water cooled and has no fans.

Also I agree with the consideration of filters. However, if your case has no intake filters or you are diligent with regular cleaning then fan orientation would be best the way SS suggested.
 
If filters are truly the only issue remaining, something as simple as women's nylon stockings can be cut and stretched over fans. I've heard of others using those *dry* Swiffer pads too. Filters can be fabricated easily and cheaply.
 
i guess it could work, since i cut the front so more airflow can get through

Its not done yet, got to paint.
