Very nice spreadsheet, I especially like that there are different values compared to who tested them.

Very nice spreadsheet. Thanks for the work. You are awesome.

Update .... New Spreadsheet V.11

http://ultrashare.net/hosting/fl/db6...8/Andrea_V11xp

The equations of the WB and of the radiators were perfected.
It is possible to push itself, with reliable results, beyond the 5 GPM of flow rate and beyond 10000 RPM.
They were introduced these new radiators marked **

XSPC RS120 **
Feser X-Changer 240 **
Feser X-Changer 120 **
Thermochill PA 120.4 **(There is in reality)
Thermochill PA 120.2 **
Thermochill PA 120.1 **
Swiftech MCR 120 **
HW Labs 360 GTX **
HW Labs 240 GTX**
HW Labs 120 GTX **
Hw Labs GT Stealth 240 **

The data are obtained with mathematical extrapolations (**)

shouldnt this be a sticky?

Can this be easily modified for Triple-SLi and more than 2 rads? (up to 4?)

Trying to run a few comparisons, separate GPU loop vrs not, and get some issues removing the CPU block, for example... I'll play with it a bit more after work.

Wow, nice work!!

would like to see HD4870 waterblocks?

The "Coeff.* Watt CPU"



To make uniform the data of two " Tester "
and to compare them among them.

A small formula mathematics is necessary.

We consider two " Tester ": A and B.

The two " Tester " measure the difference of temperature among Core CPU
and H20 of 4 WB: (WB1 WB2 WB3 and WB4).

We have that:

T.A.WB1 (temperature measured by tester A for the WB1)
T.A.WB2...... .T.A.WB3...... ..T.A.WB4
and
T.B.WB1 (temperature measured by tester B for the WB1)
T.B.WB2...... .T.B.WB3...... ..T.B.WB4

To the same Flow Rate have.......
Mathematics formula :
(T.A.WB1/T.B.WB1)=(T.A.WB2/T.B.WB2)=(T.A.WB3/T.B.WB3)=(T.A.WB4/T.B.WB4)

The relationships of the temperatures are equal to a constant K.

Calculated K......... it is easy to transform all the temperatures in (A tester temperatures)
or (B tester temperatures)

Any plans for adding additional radiator options?

[AndreaBZ]

Any plans for adding additional radiator options?

Three radiators?
It seems to me excessive.
To modify the Spreadsheet to insert three radiators
it is simple for the flow rate
it is complicated for the temperatures.
Which are the radiators?
It is more soldier to insert a new radiator corresponding to the sum of others two
If you tell me what radiators I can make a revision of the spreadsheet.

You see answer above

[Hondacity]

andreabz i've been reading the coeff*watt info..i can't figure it out exactly...

say my i920 is 300w and i'm using the ek supreme,,, what should i put in the coeff*watt?

wattage to the rad is total watts in the loop right?

excellent work

Could you add GPU temp?

ADDED: Your spreadsheet doesn't seem to take flow into account when calculating radiator performance. Could you fix it?

The data published are too much little.

.................................................. .............

You are right.
Unfortunately the " testers " don't furnish data
on the variation of the thermal resistance of the radiators to vary some flow rate.

The only information until furnished by Thermochill.........
http://www.thermochill.com/PATesting/index.php#PA1202



it don't give numerical data.
The variation between 1.0 GPM and 2.0 GPM is really least.
In the next version of the spreadsheet i could impose
a similar equal variation for all the radiators.
Does it seem to you correct?

This problem also concerns the Water Block.
Only "Next Hardware" furnishes data on the variation of the thermal resistance of the WB to vary some flow rate.
To calculate the variation of the thermal resistance of the WB tested by "Martin = MLL"
i have used an artifice:
a curve that is the average of the curves of the WBs tested by "Next Hardware".


I have used an software of translation Italian> English.....
I hope that you can understand.

The Spreadsheet doesn't point out the exact temperature of the CPU,
but it calculates the difference of temperature among a system and another,
between a component and another.
If you want that the Spreadsheet points out the same temperature that points out your PC
with core temp............
1.... to exactly point out temperature of the room,RPM fans and watt radiator.
(yes...... .wattage to the rad is total watts in the loop)
2.... to check that temperature points out core temp with the cpu in full load
3.....to modify coeff*Watt cpu so that the spreadsheet points out the same temperature
pointed out by core temp.

Or ,if you have a thermometer to measure the temperature of the water.
You calculate difference among temperature cpu and temperature of the room
modifying coeff*Watt CPU you do it coincide with ______ CPU_______ C°/W*Watt
what you read aloft to the right

Andrea, very good work on the spreadsheet and testing
What is the water block in the above picture?
