Overclocking Advice

[Guest]

Before i start im sorry this post is so long

Ive decided to buy a new athlon palomino system.
Before i buy the new cpu/motherboard ive decided to build a watercooling system so that i can overclock without too much noise.

There where three things i wanted my watercooler to do

1-Be totaly enclosed in my case (full tower) so that i can take it to a LAN.
2-Give great cooling performance allowing me to overclock
3-Be reliable and safe (probably the most important)

Ive decided to make my own radiator out of 15mm copper pipe. Ive allready started to make it and ive fitted 3m of tube into the top of my case. Ive used thin metal gause to increase the surface area, and i have room for 3 12cm fans ans 6 80mm fans to blow/suck the radiator. (im not going to have that many fans probably just 3 x 12cm fans and 6 holes but ill be able to fit more if necicary)
I have fitted got a 1.3L header tank in there too giving a approximate water volume of 2 litres.

The pump i have chosen is the Eheim 1048 600l/h @ 1.5m as it has been recomended elsewhere. The pump will turn on automatically using a relay, and i will be able to alter the flow rate usin a light dimmer switch (i think).

The waterblock is the most difficult to decide on, my current favorite is the swiftech MCW462B as it has good mountings and is annodised (to avoid electrolytic corrosion) I live in the UK so i might not be able to get one, so if anyone has an alternative please tell me.

Most of my piping will be 15mm to allow a high flow rate.

Im not using a peltier at first although i may do in the future, depending on how i do without one.

I would just like to know if anyone has any tips, recomemdations or advice. Or if you think i should use other components. If you think my design is poor, i need to know.

Thanks allot for any replies

OK, I'm not an expert but have recently just done a watercooling project myself, although mine isnt enclosed in my case, details of the project are on <A HREF="http://www.calvsplace.cwc.net" target="_new">my site</A> Im in UK also and ended up getting my waterblock from www.dangerden.com in usa as I couldnt find one that I liked over here, they do a few, I got the maze2 which comes with an extra copper plate so you can use a pelt. Im not sure how much water flow you will need, I'm using the eheim 1250 (was reccommended to me) and as you will see if you look on the site, my temps are good (running at stock speed/voltage (1000x 10) I get about 27C and running at 136 x 10 @ 2V core I get about 36C if I remember right (im at work now)- the temps are running prime95 but idle temp is actually only a little bit lower. Many people will say the rad is the most important part, I suppose it is and to this end I would take great care making yours, maplins do a temp guage (again, shown on the fron of my pc on my site) for a tennerm it may be worth you investing in one to keep an eye on the water temp.
Dunno if I've been of any help, but I hope your project goes well.

A while back I undertook a home project to make myself a completely homemade watercooler. I made it, but haven't implemented it as of yet. I am revising the "heatsink" part to be used on my latest CPU. I am using a 12V Marine freshwater pump which is something like 2-4 L/min in order to keep the pressure from getting too high. I bought a small car transmission cooler for my radiator and am currently modifying a Globalwin CAK38 copper HS/FAN for the heatsink. I have an Inwin full ATX case that everything fits into nicely (although it makes for a heavy beast). I grabbed a row of 4 quiet fans from work to mount to the transmission cooler at the top of the case for best heat exhaust. I am soldering 1/4" copper tubing through the copper heatsink with the idea being that my system will work as a normal aircooled comp until I need more cooling. Say I turn on Unreal Tournament, I flip my pump switch and cool things down. Ideally I plan to make additional water cooling plates for my IBM RAIDed drives as they get DAMN hot. I can just solder up copper tubing to some plates and voila. Like I said I have the system working and it is pretty cool. To test it I took a large propane torch and torched the heatsink for 20 seconds or so. I let it run, took off the torch for about 5 seconds, and the heatsink was roomtemp again. How cool is that? Well anyways, good luck!

I just read your site, Wow thats quite a setup you have.

You are using a similar pump to the one i have chosen. I got a bit worried when i read that your example leaked. Do you think that yours could have been fixed or should i try to find another pump ? I cant afford to have a leaking pump as its going to be inside my case.

Also, why did you choose the maze block over the others and how much did it cost? I can order one from the US although im not sure how much postage will be.

Ive added the copper header tank to my radiator today and ive increased the water volume to over 2.5litres, will that be enough or should i add a second tank ?

Im going to buy a temp guage with several sensors and then swich between them with a rotary swich. Ive allready got 4 potentiomiters to alter fan speed so once i add more fans, the temp swich and the pump speed swich i will have about 10 dials on my case(i better make some lables)

Thanks for the advice, great website too.

Do you have a problem with condensation? Do you know when condensation occurs. I've always heard it has something to do with the dew point and stuff??

Hi, sorry it took so long for me to reply,
I dont know why the pump leaked, it was brand new so I suppose if I hadnt changed my plan and submreged it I could have taken it back, the Eheims seem to be reccomended by everyone- including the fish shop I got it from, also it is VERY quiet (bit noisy till the water starts flowing)
I chose the maze as it uses the 4 bolts to secure it to the board rather than one of those "hold down devices", I've never used one but I thought the 4 bolts looked a lot more secure and also as I have an athlon (fragile core) I thought that being able to screw it down evenly would be an advantage, I got mine from www.dangerden.com , I cant remember what it came to in £ but was $21 I think for postage which is a bit steep I know.
I really couldnt say weather you will have enough water, as you have a radiator and I dont, I DO know though, that a little cpu can heat up 80 litres of water!!!!, I'm glad in a way that I had the pump problem or I'd only have 40 litres and that may not have been enough, it only raises the water by a few degrees after several hours, but even so... Once I get my new PSU I may up the voltage some more in which case I may get a radiator too (this will also be under the floor)
I'm glad you like <A HREF="http://www.calvsplace.cwc.net" target="_new">my site</A>, I've changed it a bit now- got better menus, I just need more stuff to put on it!!
If you have any questions that dont get answered here, feel free to mail me from my site and I'll try to help.
