Water block question

[Yoric]

I am trying to decide which waterblock I am going to use for a home made cooling setup and I was wondering if anyone could help me decide.

I have narrowed it to either a becooling jagged edge waterblock or a v-tuned block from overclock-watercool.com.

the jagged edge seems to perform well but I have yet to see more than one review on the v-tuned block

I asked for recommendations on a waterblock a few days ago and everyone said go with a dangerden...so I got a Maze2-1, which is the inwards/outwards spiral and has capabilities for one or no peltiers. Ended up costing me around $75 with shipping :( But hopefully it's as good as I expect, I mean, just look at that thing!

I'm going with the Swifty MCW462.
It's hard to find reviews on these things but this one looks the coolest, and it's upgradable if you want to go for a pelt later.

well I am looking for something 25-50 USD with shipping so the danger den is alittle too pricy for my budget.
I have a 1.4Ghz 266FSB Athlon.

Heh, Yoric, I'm in the exact same boat as you...
Anyways...I'd have to say the cheapest and most flexible seller on the net is overclock-watercooling.com But there is one catch. This seller has had some very BAD reviews. The problem is that he's only 1 guy, and he's getting hundreds of orders. So, it took him abouit 3 days to respond to my e-mail with a few words... :(

If you have the patience....you can contatc him, and ask him if he has anything lying around. I asked him, and he says he'll try to find me a really cheap aluminium block lying around somewhere...

Check out the comments and others from other buyers here:

Okay, if you aren't patient, and you want it now, the second most cheapest heatsink I found on the net was:
http://becooling.safeshopper.com/6/11.htm?466
15.99 For a block
Add in another 10$ for the clamps

Personally, I'm trying as hard as I can to contact Chip at overclock-watercooling.com and trying to sort things out. Because, if I can, I'll save another 10-15 dollars (about an extra 25$ Canadaian) if I can buy it from there

Thanks for the help
I think I will go with overclock-watercool since I am not in need of the system anytime really soon

I also ordered the dangerden waterblock. I never heard anything said bad about this company with only good reviews. I used a homemade plastic box with an aluminum heatsink mounted inside for months. It had a couple of leaks and caused a couple of burned motherboards. Now i'm buying one so as i can stop worrying about leaks. Go for the dangerden for it cost me only $54 + shipping. But i bought the better one for the P4 with copper cold plate to add peltiers. There are cheaper ones so go check it out.

You could alwaya make your own block like I did. All you really need is some copper barstock, a hack saw, a drill (drill bits of course) and a torch. I bought enough copper for 2 maze 2 sized blocks and chip set cooling (1 foot of 2"x3/8" 2 feet of 2"x1/8") for $12 from www.onlinemetals.com. I cut it into 3.25 inch pices drilled out the center of the 3/8" tapped holes into the 1/8" top and then soldered on a 1/8"top and bottom. I guess you need one more tool a 1/4" NPT tap for the threads in the holes. I probably spent $25 on the tap, copper, torch and fittings, and I made two cpu blocks and a north bridge block and I have enough spare for a GPU blosk if I get a card that needs it. If you like do it yourself type stuff it was great fun!

Becooling's waterblock its really neat! in fact I just bought me a whole kit from them ;)

Owenator,
have you figured the C/W for your home-made setup?
I want to compare it to the $60 water block I just bought.

Why is it that no one installs a thermal probe in the water line to determan the waterblocks C/W rating alone? I hate watercooling "system" C/W ratings . . . .

How would putting a probe in the waterline isolate the waterblocks C/W? Water temp is affected by the other components of the 'system' as well.

dan You measure the tempurature of the water that is entering the waterblock, this is like the ambient air temperature is to a HSF.

It=Waterblock inlet temp
Ct=CPU temp
L=CPU wattage under full load

(Ct-It)/L=C/W

Simple as that! This is the proper way to compare waterblocks . . .

thanx,
I've never thought of that.

Now, how do I measure that temp (It)?

I think I've seen probes that can so that but they seem like such a pain in the ass.

You need to tell that to the people who write the waterblock reviews here. It'd be nice to have some concrete way to compare waterblocks. I just had to guess on which one I thought would work better.

Just get a small plastic tube(Ideally one that doesn't restric flow too much), drill a hole just big enough for the head of a thermistor to fit through, stick the thermistor in the hole, and epoxy around it. Then put the tube in the line just before the waterblock. AFAIK the thermistor shouldn't have any problems contacting the water directly.

That's a good Idea about letting reviewers know about this, think I'll drop Joe C. and E-mail with a plug to this thread . . . .

I think you guys have way too much money for your own good :D

The room temp is 24C and the load temp is 40C with my Duron @ 1064 @ 1.85 V (really 1.94 V from MBM) something like 58 W from Radiate I calculate (40-24)/58 and I get ~.276 C/W. I think that's how C/W is calcuated? Basically I get about 11C over ambient at idle and another 5C at load for about 16C above room temp for my CPU. The case temp is always within 1-2C of the room so C/W would be lower if I use case temp of 26C leads to a ~ .2412 C/W. Mind I am useing thr onboard temp for thr CPU and a Radio Shack Indoor outdoot thermometer for case temp. Actually I had to replace the on board thermistor with a 10K Ohm one from RS after I broke th old one off bending it. I compared it's resistance to the old one at a few temps and the 10K was identical but until I get a digital thermometer I would say I am probably off, but in the ball park. Hope this helps.

alright people after a couple of hrs installing the new Z4 the Aqua Sink and the Motherboard Water block.. All Bought from overclockershideout.com. I also purchase the Universal Hold Down Device And let me tell U it doesn't work with the Z4 nice with the maze just remember not to tighten it too much or SNAP U break the side parts on the cpu Just like I did anyway I fixed the problem buy buying some Plexiglass and made my own hold down devise with the 4 bolts around the Cpu. I think its a lot better then the side clips.. now for the temps... Notice the difference I bought a prob for all the test and its sitting right next to the core.. the system Z4 cooler with 156watt pelter and a 72 watt on the motherboard...

amd 1.4 overclocker to 1500 just for start
512 PC2100
GeForce2 pro 64 Getting the GeForce 3 ti
10000rpm HD maxtor SUCKS its The 2nd one from them and I hear clicking noises coming from the HD again after 3/4 full..

Temps at idle are from of CPU next to core is 15.2c back of Cpu is 28.0c
motherboard temps idle 14.4C not Bad:D

load CPU core temp 16.9c and back of Cpu is 31.0c
load Motherboard temps 17.0c

Z4 Is better then maze2-1 in all ways...
cool better and transfer heat real nice... no big difference in temps... Well this is the test I will be doing another test with the Z4 and the overclock-watercool new Block as soon as it comes out... replies welcome.. .Blackbox AKA wolfsid

Hack the World :cool:
