My Little River - Rapids Waterblock quickie review

[MichaelMuck]

Just got done installing my w/c stuff, and thought I would give u a quick review of this block. Had a nice air setup before, so I will use those numbers to compare.

old setup:

swiftech 462-u h/s
80m delta 68cfm
as3

new setup:

Little River - Rapids w/b
1/2 tubing
dtek h/c
via 1300 pump
ac3

This in a li lan 60 case (pain in the ^$#@$% to install the h/c) with 2 120mx38m 126cfm fans, 1 side in , top out. Running my rig at 11x210 @ 1.85v

prime95 Torture test:

old setup:

idle - 37c
load - 46c

new setup:

idle 27c
load 31c

As u can tell Im a happy guy. Need to improve my airflow thru h/c and I think I can drop the temps some more.

As u can tell Im a happy guy.

Indeed you are! One thing, what are your room (rad air intake) temps? Are those results for the same room temp?

[MichaelMuck]

temps were 66f

Close to the same results i get with my swiftech set up with 3/8 od tubing

I have a 1GHz Morgan core Duron here, that at 1.85v and 1100MHz registers 23.0C on-die temp under full load for an hour (BurnK7) with 23.6C water temps and a 22.5C room temperature.

Am I really achieving better than the coolant temperature cooling? Or is my on-die thermal sensor just inaccurate? If mine is inaccurate, then what makes other people's thermal sensors accurate/inaccurate? If they are all potentially inaccurate, then how can absolute temperatures be used to make a comparison between two different systems with any degree of confidence?

Agreed ! That is why Bill Adams tests are going to be so important in time. If enough people start asking the outfits like danger den, swiftech ect. enough pointed questions then they to will have to get some high resolution testing done as well. Then we will have the best idea we've ever had as to what the better blocks are. Will be nice if it comes to pass..

.6 over water temps ..Thats one hell of a Rad

Uh, 1.1C over room temps actually. It is a Duron, and the rad looks like this:

(Image too large to post in-line here)

Dual 12cm fans sucking through a '87 Toyota Camry heater-core with shroud and internal baffle to ensure each fan acts on its own section of the core without interfering with the other fan. The core has a very high fin-fold density (24 fins per inch). All up, the core itself has close to double the effectual air-contact surface area that the Chevette core that most people use has.
