2 x 120.1 rads joined?

Tosk · 28 Oct 2006 at 04:31

hi would 2 x 120.1 rads joined to gether work ok? with a good pump to cool and cpu and a gfx card?

or is it a bad idea to join up rads? of any kind for water cooling?

thanks for any help

some think like this i was thinking

would'nt 120.2 rad better suited for your needs?

too much hassle for the increase (if any any) you'll see, you'd be better off tweaking the setup you've already got

I would guess that 2x 120.1 rads will cool very closely to a 120.2 rad but there will be more resistance to the flow of water so might need to use a better and stronger pump.

i see ok thanks guys

However, the surface area of 2X120.1 rad is bigger than a single 120.2rad.

Also, there are known advantage of running 2 rads in parallel.

But the performance increase of running in parallel is minimial because of the pressure loss from the extra fittings. But if you do want to run 2 rads in parallel, the length of the tubing going to both the rads have to be the same, otherwise, their resistance will different. This cause the flow to the 2 radiators to be different, which isn't a good thing.

I assume from your diagram that you want 2X 120.1 because of the dimension of the space you want to fit in.

If that's the case, it'll be impossible to keep the length of the tubings the same. Run them in series, you'll see better performance than a 120.2 rad simply from the bigger surface area.

Hope this answers your question.

Could you name on for me please

thx nicholas_yiu yes i was thinking of mounting them in a rom cage and mounting them like my drawing would save on the space used.

still unsure if im going water-cooling yet. thanks for the info

However, the surface area of 2X120.1 rad is bigger than a single 120.2rad.

Overgeneralising - that only applies to SOME brands of radiator. For others, it's identical. Pressure drop will be doubled using 2 radiators vs the same radiator but a natively double version thereof. This will reduce flow and turbulence within the radiators and thus reduce performance. Better from a performance standpoint to use a 2x120 rad than 2x 120 rads.

Would a PA160 fit in that space if length is an issue?
