Fan headers which the pumps are plugged into a lot of the time may not be set to give the pump its full voltage (when i said full speed what I meant was full voltage) and running with low voltage can cause the pump to rotate slower, causing the cooling fluid to not cycle fast enough, which causes the temps of the gpu to increase. This is one reason the temps are not as they should be. Its ok to go off a fan header but to remove that as the issue plug the pump into the psu directly via molex. There is no question of low voltage now thumb.gif

For the second paragraph, Unless you provide something that states otherwise id say the hybrid option provides adequate cooling of the vrm, it also cools the die far better than any stock air solution so the win goes to the hybrid unit.

You will know if there is air bubbles in your clc cause it will drive you nuts mad.gif My H70 never made a peep for .... well since they launched them like three years ago. Two weeks ago I went from zipstraps to a mount and BAM, I have bubbles now. The rad is just sitting at the bottom of the case currently. If I pick it up and tilt/move it there is a little noise like water rushing and the noise goes away.

Air bubbles in the pump are a Catastrophic Failure, not a performance hit.
You might hear the pump whine as its speed doubles or more, while your temperature maxes out.
You can get gurgling sounds when air is stuck in the hoses or the radiator hose end.
Of course, gurgling may lead to passing a bubble into the pump.
It may also reduce water flow rate.
The best place for air bubbles is the radiators tank end without the hoses.
It helps to place the RAD so that part of the tank is above the pump.
If the hoses exit from the pump bottom you could still trap air in the pump, especially as you move things around to bolt it down.
It's just a matter of moving the RAD and pump around so the air can rise up to the RAD before bolting everything down. Tapping on pump it will help too.
If everthing is already bolted down then tilting the whole system around can fix it. It just takes a little imagination.

My imagination is really on the nay side. If you can provide a simple diagram, it would really be worth a thousand words for me.

So if I plan on installing the rad of my AIO system on the bottom fan slot of my case, will their be possible formation of air bubbles?

Gocha, so usually we always want the pump to run at full power, right?

I was actually referring to the VRAM modules AKA memory modules, not VRM circuitry? Hope you can help me answer that question.

So there's really no way of avoiding those air bubbles before installing the unit to my card?

Diagram? I'm not an artist. I'm a mechanic, tech, lab rat, engineer, and shop teachers son.
Air rises, and you tilt the system to change "What's Up Doc".
Up and out of the pump (light tapping with pencil wil help) and into the hoses.
Up and out of the hoses and into the radiator.
Up and into the other end of the radiator.
Just be the bubble.

There is always a possibility of air bubbles, eventually. "Low Permeability" hoses are used, but they are not perfect. Eventually your Closed Loop Cooling system will lose water and it will be replaced by air. Many people here do put the rad on the bottom, but I won't.

Ok. What did you mean by "if the hoses exit from the pump bottom" ? Where is the pump bottom? Or do you mean if the rad is below the pump?

I thought air will be mostly trapped in the rad if it is placed horizontally whether above or below the pump?

Any ideas on my thread here: www.overclock.net/t/1347517/arctic-cooling-accelero-hybrid-cooler-pump-noise ?

does this make the card a 3slot card? or will it say a 2slot?

Could somebody tell me whether the h60 will line up with holes in the the 670 pcb? I want to try this mod, but I want to get it fixed on there properly. Otherwise I won't start the mod... thanks

it will stay at 2 slots. i have dwoods fan bracket on both of my gtx570s and they fit a little bit snug, but it works
