70's while folding? - Page 2

post #11 of 20
Yea thats a bit warm considering your OC.

Did notice you have quite a bit of rad there, you might benefit from some more, but I wonder if your pump is struggling with the loop a bit.

What pump do you have? (sorry if you said and I missed it)

And are your GPUs series or parallel?


You might benefit from putting the GPUs in parallel if they're in series (reduce the restriction 4 fold) or from a larger pump.

I have 2 MCP655's and the whole loop is in serial. I see a lot of "swooshing" in the res, so I know flow is good. The Vid cards would also be a lot higher (and they are OC'd to 951 core/ 1902 Sharder/ 2103 Mem) if that was the case. I'm pretty sure the block has too much paste (put a little more than a grain of rice).

I do like the idea of a parallel loop however. Might need to buy two more Koolance SLI extenders... hrmmm. I'll look into that tonight!

Thanks!

Since your system is under full GPU and CPU load all the time, and you have 3 video cards, you would likely be better off if you split the loop into 2 loops, one for the CPU and one for the GPU's.

That's reserved for my next build in a caselabs or a Little Devil... Or even an outdoor waterchiller. =P

On another topic, you mentioned that you were -bigadv folding on the CPU.
With 3 video cards in the system, I think you may find that you get better PPD from just regular SMP folding on the CPU than bigadv.

I realize your CPU, at your current OC, is a slightly faster folder, but just adding a 2nd video card to my system increased my TPF substantially on bigadv work units, to the point where I think I'm better off just doing SMP.
I'm having a go at a week of it each way to be sure.

Yeah I noticed I get 4k less PPD on -bigadv. Don't you get bonus points for those, which makes it worth while?!

On topic, I<m pretty sure adding the 3 vids in parallel will help with flow and temps. I will also try to reseat the block (I still have some Shin Etsu left).

your 140.2 rad is in a pointless position, put it before the cpu, even if its 120 > 140.2 > cpu > res > pump >200 rad > gpu's > back to the 120

Having a Rad between the cpu & res is pointless... The way it reads you have a 200mm cooling 2 gpu's, a 120mm cooling the cpu and a 140.2 cooling the res & pump...

You dont need to cool the res & pump

The best placement of rads is right before a cpu or gpu

loop order does not matter, the water reaches equilibrium after awhile and doesnt make a difference if you have rads before or after anything.

res->pump is the only thing that matters

Umm, if you haven't qualified for bonus points on bigadv, don't do them, lol.
Do 10 regular SMP units using the same passkey to qualify for bonus points, then switch.
Doing 10 regular SMP, you can qualify in 2-3 days, doing 10 bigadv units, it will take more like 20 to 30 days..

Bloody hell, that's not the issue then!

And there was me concerned that you had some silly little rasa pump.

Since you have 2 pumps though dual loops might be an interesting option to try out if you have the inclination.

All things considered though, I think you would prob see some benefit from a little more rad space. It's a bit hard to say really, there's so many factors, and without knowing your ambient and coolant temps....



As for folding points, you get the bonus points anyway, it's just a multiplier to what you'd get anyway. It's just a lot more obvious on the bigadv (I think, I guess there is always the chance you get less of a bonus compared to bigadv)
