Water Block II

[MiseryQ]

Since my first experiment in WCing did'nt go to good I decided to make a block instead of going direct die again...

Please give your ideas on how this might work... I'm rather anxious to try it and it won't be ready until late Friday... 24hrs to dry, 24hr leak test...

I used a heatsink from an old 8meg Savage4 that I flashed with the wrong bios awhile ago... Cleared the plug from a pvc 4" end cap enough to get it in,,, then pressed and marine Gooped the 1/2" fittings into it...

Just in case anyone might be interested, While at Home Depot I came across some fitting used in sprinkler systems called "funny" fittings,,, I don't know why... They seem pretty well made... The interior is very smooth and contoured and the threads are sharp,,, They come in different shapes and looks like they might be useful instead of brass...

Thanks...

Heh, they are called "funny fittings" because you dont use piping, to connect to the watering sprinklers. You use "funny pipe" which is a plastic type tubing.

Most other systems, the sprinkler mounts right to PVC or whatever piping you are using for a watering system.

And, no. The "funny pipe", wont be good for water cooling systems.

Ok, I'll shut up now. :D

[MiseryQ]

I saw the funny pipes too... You can bend them and they don't collapse... But I don't see where they could be worked into a WC system either...


DNS2Go seems to be having problems today... If the link above does'nt work this will...

hey, i used the same fittings with my Danner 250gph water pump. it works great, plus it matched the color of the pump. just use some teflon tape or paste to seal it.

[MiseryQ]

I need some advice...

I have the block installed... Grease on the sink, nuts on the hold down tightend to the same height... The computer shut down when trying to run Sandra MultiMedia the first time...


I knew I was'nt getting enough flow so I drilled out the shower head larger, changed the fitting on it, and shortend the bong to 24" from 36"... I got more pressure...

Now the temps are running at 127F to 131F STANDING... IF I lay the computer on its side the temps drop to 123F to 127F... ?!? The 1/2" lines are'nt as cool as they were so I assume I'm actual transfering some heat now... With the GlobalWin cooler I was using, temps ranged from 111F to 131F...


Now it's official,,, I don't have a clue as what I'm doing... But I'm having fun :D... Maybe not enough flow?!? Why would the temps drop when I lay the case down?!? Maybe air in the block?!? Any other suggestions?!?

Misery the only thing I can think of is poor/ inconsistant contact with the processor. Check to see if the tubing to the processor is binding or pushing away when you get it connected. If you think they might be that could be part of it........
Hey Sour I used them too and like he said the cool part was the color matched the pump, and they are DIRT cheap. I never found a problem with them running water above freezing temps below ...now maybe that could be an issue.

Hey MiseryQ, is your bong on the floor with the computer on the desk? You might be having flow problems from pumping too high.
The easy way to find out is to put the bong on the desk next to the computer, hoses and all. If your temps drop further, you may not have enough arse in yur pump.
If this is the case, you can just leave the bong on the desk, put the computer on the floor, or get a larger pump. A 24" bong isn't so big it couldn't reside on the desk permanently.

Just a thought. Glad to see your having fun experimenting though. This "Geek Sport" has a grand mad (or angry) scientist feel to it.:D

[MiseryQ]

Yes it does... And trying to find parts people keep asking "what are you doing?" Then the looks start... At loews the other night the for the first time the guy helped and did'nt say anything... I thanked him and said: "your the first how did'nt ask" he said "I saw the motherboard and figured I did'nt what to". LOL...


The Bong is on the floor on so the computer... It has over 7 gallons of water in it so putting it on the desk is not an option :D...

I gonna dry the the pump out then go upgrade to a 250 inline... I'm also gonna check the contact with the processor and the grease... I bought a new batch from RS and it seems to differrent than the old stuff...

I don't like to say this, but I suspect that you water block won't work well, even in optimal conditions.
It could be that your water is going into the block, going over the heatsink (not through it) and going right back out without taking much heat away from the heatsink.
Since you've already got the block, you should try whatever you can to make to work without ditching the block before you decide I'm right.
BTW, I hope that I'm wrong. I'd really hate to see you have to toss out something that you've put so much effort into.
Good luck.

readin your post i would say it is a problem with contact i may not move noticably but just a margional amount can cause problems. also i would suggest for maximum performance next time you get thermal compound try ASII or ASIII that should help your temps a bit.

[MiseryQ]

Thanks for the responses...

I exchaged the 190gph pump for 350gph, drilled a couple of larger holes in the shower head, lapped the sink and remounted the block VERY carefully with the old RS compund...

I booted into windows at 84.6F... :)...
After some use, no tests, yet I'm at 86F... :D...
So far 30 dergree drop... Gonna run some tests...

The block has less than .25" between the sink and the top wall...
Should I reduce this next time around?!?

I need to get over to a electronic store and get some good stuff... That latest RS compund isn't as opague as the older stuff... Hardly scientific I know...

[MiseryQ]

Seems good so far...

1569mhz up from 1512 and 102.2F under load... :D...

But now I have a new problem,,, Above 112mhzFSB the TurboII goes back to deafult speed settings... :(...

1610mhz@102.2F loaded... I love this WC stuff...

[Christoph]

Sorry about that. I didn't notice that you had such a small gap between the heatsink and the top wall. The best possible gap would of course be 0, but I don't think that your gap merits a change. Good job! I'm glad to hear that I was wrong.
BTW, do you mind posting your temps in °C? Thanks. Go here (http://www.onlineconversion.com/temperature.htm) if you don't have anything easier to use.

[MiseryQ]

Thanks... Next block I'll take it all out...

I'm running at 1610mhz@32C idle. 37c under load.
The room temp is 24.4 and the Water temp in the resv is 18.9C.

that is one cool hold down. i made a block like yours from an old heatsink but have never tested it out because i have direct die glued on. i have seen an article where someone took a 1U heatsink and turned it into a waterblock, but they put spacers in the fins to mak the water flow in a maze pattern through the fins, try it

[MiseryQ]

Uh... Thanks... The wood was my girlfriends idea after I could'nt find aluminum bar...

How large is a 1U heatsink?!? Will it fit in a "cap"?!?
