So, I'm looking to liquid cool my rig, and quite new to it in computers.(I'm a diesel mechanic by trade)

Anyway, the main question I have is can I cool my cpu and graphics card with the same radiator(I know I'll need a block on my graphics card)? My idea is as follows:

Resevoir > Radiator > CPU > Graphics card > Radiator > Resevoir

Um, yea Idk im a noob
thanks.

I know nothing about water cooling, but I think it would make more sense to have it like this.

Resevoir > Radiator > CPU > Radiator > Graphics card > Resevoir

So it gets cooled down after the CPU before going into the GFX card, rather than carrying along the CPU heat into the GFX card block.

yea, you can but at the very least, you would need a rad that holds 3 120mm fans. well that is only with one rad. but if you are looking to use two rads.. i'd say... 2 240's wolud be ok? but i would still recommend atleast 1 360 rad.

So your sig rig you can expect a thermal output of ~250-300 watts depending on OC if you consider GPU/CPU. Google tdp to get an idea of how much heat a component will output @ stock or go here. A single 3x120mm rad can handle this type of heat load, but you run into the problem of heat distribution. The water rises in temp across you cpu block and your gpu gets hotter water. Fortunately the wolfdales don't put out a lot of heat (prolly <100watts OC'd) and so this equates to only a few degrees @ a reasonable flow rate.

So a 3x120mm is fine and will work well, if you want MAXIMUM cooling for your gpu you may benefit from multiple rads, but this gets tricky as different rads have different degrees of restriction(this you want to minimize as higher flow rates give better cooling). The best heat dissipation to flow restriction is achieved with larger single rads - have you seen the 480gtx?? .

Sorry for the wishy washy response, but there are several good solutions. the simplest is a single 360/480.


edit: I forgot to mention
for a single loop:
Res --> pump --> rad --> cpu --> gpu -->
for a 2 rad loop:
Res --> pump --> rad --> cpu --> rad--> gpu -->

as for pumps, either a mcp 355,$75, with a top like this XSPC res top$45, the almost as goodxspc normal top for $20, or a slightly slower/cheaper D5 vario, ~$85. The 355 with the normal top is the best price/performance imho.
