Help getting x4 630 to 4GHz

[red1776]

Does your vga setup constrict your airflow at all? Have you tried calculating the cfm in to cfm out? That's what I'm trying to do right now.

Oddly, I have. I tried it both ways but preferred a positive pressure setup. I have 210CFM in and 175CFM out. it works very well. The 3x 5850's im sure disrupt airflow, but i have a core fan in the middle of all this driving a 'tunnel' effect. I am not sure how to count the 'core fan' and the cfm in or out.

Having a negative pressure is actually better. I've done a lot of reading on it and it seems that a positive air pressure system creates static electricity from the air build up inside. I'm actually running a negative set up. You might want to read up on it if/when you get time.

Although with a positive air pressure system it will help keep dirty out of your system, just less possible cooling.

No doubt about that, negative moves more air, but i have such low temps that I opted for the 'less dust' approach. I actually have done a lot of reading on it and was vigilant about static build up, particularly with an acrylic case. It has not been the least bit of a problem though, much to my surprise.

The key to the whole 'posative pressure' approach is to allow enough 'leaks' so that the pressure is just positive, not case bulging

I've been goin for a negative setup myself. But I don't have enough out take fans on my mountain mods case. Not worried about it much now, but when I upgrade to a 980x I think it would help with static air slots on my wc'd mobo.

Sorry to the OP for kinda hi jacking the thread, jump in at any time to ask us questions!

I have stuffed all of this in a mid tower believe it or not. I am currently working on a custom acrylic full tower, and looking at water systems, including the pieces you put together a while back. Which reminds me, what size radiator am I looking at now? and 2.) where in the hell do you get that cylindrical glass reservoir tank at?

 

[LinkedKube]

The best I can find for now. I did find a few companies that will cut you one to length, the tube that is, you'd have to do the rest of the modifications yourself.

I'll keep looking though.


Which vga's would you have in the loop? Will you be using the same cpu as well?

yep, the x6 and the 3 x 5850's, chipsets as well. possibly memory



*****beautiful! that's what i was looking for. I had my own idea for the base and cap.Thanks

Wow this is a project then.

Read this chart http://www.xtremesystems.org/Forums/showthread.php?t=220593

and look at the op's sig as well, a bunch of useful watercooling information there as well.


I think you may need 2 seperate loops for all that. That's a lot of flow restriction. Maybe a 120.3 rad for the gpu's and a 120.2 for the cpu, mosfets, ram. Check the link out when you get a chance.

 

[red1776]

Lots of good stuff here! Swiftech is in the middle of the pack, that surprises me.

 

[LinkedKube]

Yeah I plan on getting a feser monstra rad. I already have the 120.3 exchanger and it handles my 295 and cpu well but I know I can get better temps. Plus when I add in my mosfets/nb/sb I'll need more room.

I'm just trying to decide if I want to get another 295, or just upgrade now to a better single gpu all together.

Swiftech are known for their water blocks mostly, not so much their radiators.

 

[red1776]

and now the dumb question...
cooling wise, is there a difference in how one system will respond to an AMD as opposed to an Intel chipset besides just heat dissipation...I mean as far as cooling characteristics because of design? might one rad dissipate more heat on an intel as opposed to an AMD?
any idea what i mean? LOL

**** I think you will kick yourself if you don't go DX11, its in its infancy, but the effects look very promising.

 

[LinkedKube]

Not really. First thing to do is to look up how much heat dissipation the rad you want to use can handle(rated in watts). If you think you're going to go over the maximum heat dissipation of your rad with what you're putting in the loop you can calculate it with simple math by finding the max watts used by your cpu and gpu at full load. The mosfets are a bit harder to add in, but I was told over at extremeoverclockers to add 200 watts for a modern amd system and 240-250 watts for an i7 setup.

Also remember that the rad is usually only as good as the optimum cfm that you can move through it as well.

edit* oh and to answer your question directly "yes," there's a difference. i7's dont require much tweaking to the northbridge to get a maximum overclock because the memory controller was moved to the cpu. I know you still have to do some tweaking with your amd setup.

 

[red1776]

Yeah, +.10v is pretty standard to the NB/HT to stabilize anything over 25%

Phenoms love the cool. If you can keep the load temps around the mid 40C's, you will get great results.
A name brand psu is a must if you care anything for your expensive hardware inside the case. If the psu fails, there is a good chance it will take everything else with it.
Run Prime95 or OCCT and watch your temps.
What cooling did the guy have to get 4.4 out of that chip? I would bet it was something exotic like dry ice or phase change cooling.
