Slightly Modified P180

[Eastcoasthandle]

Hello,

I finally decided to cut 2' 2" from my loop and mod my P180 to accommodate the smaller loop. Here are a few photos. The loop is cloudy because there are still bubbles in the loop at the time the photo was taken

This is a close up of the 2 holes that I drilled. If you noticed I switch the order of how it enters the rad only because the tube would kink if I used the normal method. In all this worked best.

this shows the tools I used as well as how much tubing I cut which is 2' 2"

In order to fit the rubber hole gormments I had to drill a 1" hole in order to accommodate 3/4" gormment. Keep that in mind if you want to drill holes in your case. Also note that you want to buy a metal/wood not the wood kind. You will know you have the right tool because it costs more :p:

Needless to say its still a work in progress.

thoughts?

temps before? temps after?

temps before? temps after?
I am still bleeding the loop but once all is well again I will post temps. Although I don't expect anything new regarding ambient and load temps as a whole.

Ok, I decided to clean the tubes as they were dirty

Update:

I was getting way to much restriction using a 1/2" T. What I found out is the 1/2" T is the OD and not the ID. So I visited my local hardware store and picked up a copper (could be brass not sure) 3/4" by 3/4" by 3/4" T that has a 1/2" ID.

Using a Tygon 1/2" ID and 3/4" OD tubing. Surprisingly enough the tygon 3/4" OD, 1/2" ID tubing fits like a charm and I could push it all the way in without much resistance.

After I refilled the Loop with water the first thing I notice was the fact that it it took a lot more liquid then normal. Bleeding of the loop was faster then expected and I was able to start my computer in about 25 minutes of bleeding. So far after an 1 hour the bubbles are almost gone after shaking the rad a few times.

If you are using 1/2" ID tubing I serious recommend that you get a 3/4" T as most 3/4" T already have 1/2" ID by design. Do not use 1/2" T because that only tells you that the OD (outer Diameter) is 1/2". The ID (inner diameter) of a 1/2" T is 3/8". So unless you are using 3/8" ID tubing 1/2" Ts are fine to use!
Here is a photo of the old T

Ok, after about 1 hour 40 minutes bleeding is complete and I took some temp readings (using the 3/4" OD 1/2" ID T). Before bleeding was roughly 6.5 to 7 hours on average with the 1/2" T with the 3/8" ID.

Before, with the extra 2' 2" of loop and 1/2" T with 3/8" ID (small hole) readings are as follows:

Ambient is 25C

-x1900xtx OC 733.5 GPU and 833 MEM
idle 33C and 41C using RTHDTIBL
VC temps is 38C

-660 OC from 3.6 to 4.36GHz
idle 37C and 42.5C using Prime95
MB temps is 27C

Now, with 2' 2" less tubing in the loop making it roughly 6'-7' with 3/4" T with 1/2" ID

AMBIENT TEMPS ARE 30C

x1900xtx OC 733.5 GPU and 833 MEM
-idle temps 35.6C
http://i11.photobucket.com/albums/a154/eastcoasthandle/WATER%20COOLING/idle_temps_VC.jpg

-Load temps 43.6
http://i11.photobucket.com/albums/a154/eastcoasthandle/WATER%20COOLING/load_temps_VC_43_6.jpg


-660 OC from 3.6 to 4.36GHz
-idle temps 38C
http://i11.photobucket.com/albums/a154/eastcoasthandle/WATER%20COOLING/idle_temps_CPU_edited-1.jpg

-Load temps 44.5C
http://i11.photobucket.com/albums/a154/eastcoasthandle/WATER%20COOLING/load_temps_CPU_44_5.jpg

In all in overall improvement even though there is disparity of 5C hotter on ambient, load temps for:
x1900xtx = 2.6C difference with ambient temps being 5C hotter
660 OC 4.36 = 2.0C difference with ambient temps being 5C hotter. Again, the only difference is:
-2' 2" less tubing
-only using distilled water this time
-used 3/4" T with 1/2" instead of 1/2" T with3/8" ID inwhich there is no restriction
That is basically all that I have changed in this WC setup

very nice T there, do you know the name of your local hardware so I can go and pick one or two up

I visited a hardware store called Lowes (http://www.lowes.com/lowes/lkn?action).

[Eastcoasthandle]

does anyone have any suggestions?

[nikhsub1]

From www.mcmaster.com part # 5463K613 is a black nylon tee fitting, 5/8" OD 1/2" ID... tis what I use. $5.71 sold in packs of 10, so 57 cents each.

[Eastcoasthandle]

has anyone converted their T's

Are you sure there is no more air in the system? I know when I refill mine my temps are always the first days - I've always just attributed to small air pockets that might still be in the system, even though I shake everything like hell when Im bleeding it.

I'd say let it run 24/7 for a few days and see what happens - also depending on where you are, are the ambient temps any warmer? I'm in Buffalo NY and it's been 70 - 80's the last few days so my room is hotter - my temps are up about 5 degrees right now as well.

It's very muggy here in MD today. In this room it's around 93F so I might have to turn on the ac. :slapass:

But as of today, no more bubbles from the rad after tapping it a few times.
Should I be concern that the water is getting warm/hot??

Where at in MD?

I am just orth of you, in PA, it was muggy here as well...........I miss winter!

near towson area...

[phelan1777]

near towson area...
I lived in Calvert for about 3-4 years, then moved up yp just south of Baltimore.

I hated every humid day!

[Eastcoasthandle]

well it looks like we are in for some humid days ahead of us...so glad I am WC now. But I may need to look on the inside of my storm

[vegabros]

How do you get ambient temps? Is that just your room temp or the case temp?

I'm using systool... but I don't see it.

Thanks,
