does cooling actually increase efficiency?

[HolyGhost23]

if i ran two of the same chips at the exact same wattage/voltage. but one was watercooled and the other one was just a heat sink. would you actually notice a measurable difference in how well the chips ran. "less power consumed". but more importantly would this translate to real world money savings. and if so is it worth the cost of better cooling?

would it put out more light?

absolutely

would it be more efficient? maybe. it aint free to run fans and water pumps

if you have a 100W chip and you can get 5% more output out of it by running 5W of cooling apparatus, wheres the savings?

If the fan is running 2 watts you only need about 300 more lumens to cover the extra power. Efficiency is about break even with the benefit of cooler chips and a bit more light.

It`s not only more efficient - it also save life hours too - have a lock to the diagramm
A good waterpump needs as less power as posible. It´s enough just to move eg. 200 liters/h -
so you can cool a 2500 W lamp with just 2,3 W (0.1% of total power) aquarium-waterpump. In a closed circuit of liquid you don`t need much pressure or powerbomb. And now the most important ! :
Use the hot water for many things like: saving your roots in winter or bring out the heat in summer or prepare grandma a hot bathtube. The efficency of a watercooled led-light can easyly rise 30~50% if you use it for waterheating too.
Produce your electricity by wind and sun - and you can step down forwards efficency.
--- and then blow this all in the cold ass of the cole-lobby and our blond cool world-leader to make them catch a cold and - too sick to survive. Cherio

looks fun id like to see that with an hq cob

an aquarium pump isn't rated for hot water. It would'nt last long.

You are right - hot water is not good for happy fish. The pump will not work longlife with very hot water. But up to 35° it shouldn`t be a problem. So you have the posibility to rise the volume of watercircuit number1 (good is a min. of 10 liters/100W of lamp-power - or installing a room-fountain to rise vaporisation), or to cool with a radiator in a second + cool watercircuit - to make shure that water going through the pump is cool enough for the pump and the chips. I connected / Temperature control switch KSD9700 50 degrees 250V 5A Normally open thermal protector / to block the system for higher temp. 50° will show me that there is something wrong with the cooling-system.
