Good Godfrey Martinm210... are you a robot?

+ for that excellent piece of info.

I missed him calling head pressure.......Thats about what I get on a CPU only loop at load is a 1C drop across the rad...Idle 1.5-2.5C, thats with high cfm fans to...Even on TEC with a little over 500W load it would usually run about 1.5C drop across the rad loaded and idle 2 or 3C, something like that I really don't remember the idle temp's...

Good stuff Martin, I guess those little probes I have are pretty accurate...I remember J Mc suggesting the Crystal Fontz to you...How do you like them?

EDIT: OP an easy way to remember head is this,Head/Energy/Velocity....The more energy and velocity that you can keep in your blocks and rads the cooler you should run...The more head/energy/velocity that is scrubbed off by components that are not directly related to cooling (rad) or picking up heat (blocks) is cooling lost...PSI is force...

Whoa!! I wasn't advocating any loop order based on some supposed head pressure advantages. That's just the 2nd popular "fact" that I see around the net.

That's my belief.

Found this in the Swiftech H20-220 apex Ultra Install Manual:

http://www.swiftech.com/products/ins...ultra-rev2.pdf
From a performance standpoint there is very little performance to be gained from strictly controlling the component sequence: the
maximum delta T (difference in temperature) between any two points of the liquid cooling circuit does not exceed 1ºC. Whenever
possible, performance oriented users will typically want to route the radiator discharge(s) tube(s) to the inlet of the CPU cooler, since
the fluid exiting the radiators is always the coolest.

It's great for logging temps, but I havn't figured out how to permanently setup my LCD to display temps (I can setup it up, but I loose my settings after shutting down). I think the good software still has some vista compatibility issues.

Overall I really like the accuracy of the probes and flexibility but the tool and software are not very user friendly. Before I could even use the CF unit, I had to solder on a fan header to the PCB just so I could plug in the sensors, then you have to fabricate your own sensors..etc. Then when you're playing around with the software, the interfaces feels more like programming code.

It's doing what I want it to do, but probably not something for everyone. So lots of flexibility, but no very easy to use. I get the impression all of the CF folks are programmers and the everyday user spends alot of time doing this trying to make it work..->

Martin, have you tried LCD Smartie?

I'm getting to it okay, so maybe it's back up. here's a cut-and-paste from the home page. Might help you decide if this might be of help:

Main Info

Hello and welcome to the LCD Smartie site. LCD Smartie is software for Windows that you can use to show lots of different types of information on your LCD/VFD. It supports LCD/VFD's with a Hitachi HD44780 Controller, a Matrix Orbital Serial/USB LCD, Crystalfontz Serial/USB LCD, Seetron Serial LCD/VFD, IRTrans driven VFDs, SoundGraph iMON VFDs, Futaba VFDs, Pertelian LCDs, VL System L.I.S VFDs, IEE Inc. VFDs, and PalmOS devices (when used with PalmOrb).

It can display: Everest statsMBM stats (your CPU temp, fan/cooler speed, etc), BBC World News (or any other RSS feed!), WinAmp stats (currently playing tracks title, length, position, etc), Network stats (speed, total bytes, etc), CPU Speed, Disk available/free, memory usage, Email details, game stats, and many more...

This great program is absolutely free to download right here.

Thanks...Soldering isn't bad but the rest doesn't sound like much fun......The little LCD read-outs I'm using now are really fine for keeping up with loop health I guess I'll just stick with them for now..I would like to put a probe right before CPU and the res sometime..

well that was the best loop order for me when i watercooled so that's what i always reccommend to others when they ask. putting the pump in 2nd lowered temps by 2* give or take. there was another person who noted the same thing, i can't remember who...
