TimeLord's Jet block v1 (machining pics) - Page 2

its so sexy...
this is stupid but if u gota a pool with a 24/7 pump make the water come from there. ultimate flow and coldness, athlo id hate to see what type of animals start colonising yout block (ZERG!)
anyway i was crapping on so dont take that too seriously (if u think its a good idea take it seriously by all means)

Okay... Final update to this version of the block.

Sealant is dry, Y connectors are done and system was upgraded without a hitch.

Did do some head scratching as to how to plumb this.

Here's the block in action... Water is murky from when I reversed the loop flow from pump-blocks-radiator to pump-radiator-blocks. I will be changing the water soon to distilled as I didn't have enough on hand to do this with.

Another shot of the whole system... even got part of the old waterblock in the picture.

My system temps went up after this... and I got to thinking "Now why the heck would that happen?"

Turns out that the block IS more efficient at getting the heat into the water... so much so that it made me aware of the fact I don't have enough moving air directly across my radiator. So I put a couple of 120mm fans across it and WHAM... my temps dropped by 7°C from my former average! WHOOT!

Now I think I will be revamping the ducting for the radiator box to maximize flow and lower the speed slightly of those fans or get quieter ones with better CFM flow.

Thanks to all who helped me rough this out in the beginning.

Thanks to BladeRunner to inspire me to play with my mill again.

After the ducting changes and some statistics taken on average temps (yeah, yeah, I know ... sucky accuracy & linearity) I'll make a smaller jet block and compare them.

I might throw in a couple of HDD blocks in the mean time to tax this radiator further... whaddya think?

:shrug:

I'd suggest that before starting a new block that you block all the holes in the outer two rows and then retest with just the 4 remaining lines of holes.

This will greatly increase the waters velocity and improve your cooling.

Will also give at least some idea how your next block should be changed...

Blackeagle · 09-30-2003, 02:19 PM

Am I confused, or are you running the CPU block & GPU blocks in a dual loop?

If not what is the Y fitting just before the CPU block for?

MMZ_TimeLord · 09-30-2003, 02:53 PM

I am aware of the flow issue with so many big holes... This was a prototype for baseline.

Yes, dual loops... one for the CPU one for the GPU ... split just before the CPU with that long "Y" fitting that you see. This is because the flow through the GPU block is VERY restrictive and I didn't want the flow restricted through the CPU block.

I am planning on making a couple of simple HDD blocks like this and putting them in this week.

This will go on the bottom of the HDD and the drive will be flipped over so it will now be on top with the drive upside down... this is because the casing of HDDs are aluminum and conduct heat better than the top cover which is mild steel (I think) and is insulated from the base by a seal.

it looks like he is running the cpu block and vga block in parallel.

:edit:
well i replyed about 10 seconds too late, and for some reason can't delete.

MMZ_TimeLord · 09-30-2003, 03:05 PM

Caeberos,

You are correct... they are in parallel.

I may have been mistaken about the block picking up more heat... not sure... I think I will put the old block back in with the fans in place and see if I get a lower temp. I want to let the block burn in for another day though to make sure it had "seated" properly.

Then I will switch back to the old one and verify the temp drop with the old block in parallel with the GPU.

I made a classic mistake in changing more than one thing at a time...

1. Changed the routing from series to parallel.

2. Changed the block from the old copper to the jet block.

3. Added the two 120mm fans just above the radiator.

No way to verify what did what without switching back to the old block. I might even remove the fans at first to see if the parallel plumbing helped anything with the old block.

whoa

where did you get those Y fittings?

MMZ_TimeLord · 10-01-2003, 03:13 PM

Made them from small blocks of acrylic and some acrylic tube. The tube is ½" OD and is the same size as the flexible vinyl tube.

I'm impressed. What would it cost me to acquire one of them from you?

I've got a Y connector from dtek right now ... which was better than anything I had used from home depot in the past, but yours look absolutely stellar for this application.

MMZ_TimeLord · 10-01-2003, 03:32 PM

Well, I had not planned on making more of these than I needed.

However... IF I did do some more, I would have to know what size and type of tubing/hose you are using.

Is it clear vinyl like mine?

Got KarmA? · 10-01-2003, 05:26 PM

Yeh, its 3/8" ID Tygon tubing. All the barbs in the system are 1/2" though.

I'm just curious as to how much it'd cost to make ... I doubt I'd bother disassembling the current setup and cutting new lengths of hose to accomodate a new Y.

MMZ_TimeLord · 10-02-2003, 08:39 AM

Well, between the acrylic and the vinyl tubing it probably cost less than $1 each. Just some time on my part to drill and shape the acrylic and glue the acrylic tubes in.
