I finally Desided to Join :-)

Here are my question.. I currently have a new boreas System in a lian Li Case. I replaced my pump with the Koolance 980 combo/res I like it because you can adjust the pump.. I was using a EK supreme gold cpu block on my Core I5 750 O/C to 4.1 but it so restrictive going to my GTX 295 Block. anyways.. my questions are

will a FZE help lower my temp more?
Will switching to 3/8 tubing help from the 1/4 I am using ?
I am currenly using the stock Cootit block because my EK Supreme Gold is so restrictive and my Gtx 295 was getting to 69C underload..

Sure, you can always add an extra FZE to cool down the coolant even more.
Replacing the stock pump was a good idea, the more flow the better. To find out if the EK block will perform worse/better, you can always try it and see if it does any good to your temps.

As for the tubing, the flow rate will always be related to the smallest hole in the setup. The blue Coolit-TEC-blocks are very restrictive due to their small fittings, so I think the EK block wouldn't do that much to the setup's restriction.
We found out (TIGA mostly) that the more pressure a pump can give is more important than flowrate (just read some posts back).

I'm using 5/16" ID tubing, as they fit over the blue TEC-blocks, larger tubes will also do the trick but will be a pain connecting them to the TECs, plus the flow will always adjust to the smallest ID anyway.

Just trial and error and try some stuff to find out which gives the best tems

Ok, so here is what I am going with:

HARDWARE:
EE975
X58 Classified
Mushkin Ascent Redline DDR3 1600
Soundblaster X-Fi Titanium PCI-E
2 x G.Skill Falcon SSD 128GB RAID 0
3 x EVGA GTX 280 FTW Tri-SLI
LG Blu-Ray Burner
Western Digital Elements 1.5TB External Hard Drive

CASE and COOLING:
Custom MTEC Chassis w/ Boreas and 2 x FZE
2 x MTEC Control Center
PCP&C 1.2KW PS
Koolance Blocks for 280's and Classified
Swiftech Apogee XT for the CPU
2 x Swiftech MCP355 12v DC Pump
2 x XSPC Res for the 355's
Bitspower fittings throughout
Tygon A-60-G Norprene 1/4" tubing
Either Coolit coolant, or FluidXP Nano Fluid

So...the idea is to use either the Boreas, or the double FZE to cool just the CPU, and the other to cool the chipsets/GPU's.

I was thinking to use the Boreas for the GPU's and Chipsets: Boreas>Chipset Blocks>GPU's>Res/Pump>Boreas...this way the fluid is at it's coldest when it hits the first block.

For the CPU, question here is around proper routing of the dual FZE. Was thinking: FZE1>FZE2>CPU>Res/Pump>back to FZE1. Again, thinking the fluid is at it's coldest when it hits the CPU.

I am open to swapping coolers...Boreas to CPU, twin FZE to Chipsets/GPU's if you think that is a better idea. I just like the idea of being able to plug in both FZE's into the MTEC CC and control them, and have the Boreas running on it's own without the MTEC CC monitoring (wish Coolit would come up with a MTEC CC that can control many cooling units!)

Question for the experts on the fluid...I like the Nano Fluid because it's non-conductive, and seems to have the same corrosion inhibition as the stock fluid...thoughts? Temp issues? Corrosion Issues?

Also...you'll notice no radiator in the case....I wanted to keep it that way, but I am open to your thoughts on the impact of the case heat on the fluid in the res...don't really want to add a rad and fan, but open to your thoughts. If it's just a few degrees of temp, I'm ok with not having a rad in the loops.

Also...with the MTEC Chassis...shouldn't the Boreas be set up to pull air in one side, and out the other side? I noticed that both fans are set up to exhaust air out the sides....seems like cooling would be more efficient with air pulling through the system and directly out.

I put the FZE's at the bottom, removing the HD cages an placing the FZE's on the platform at the bottom, nice and neat...but, the FZE is designed to be at the back of a case pulling air out and venting...but in this setup, I think it would be better since there is mesh in front and behind the FZE's to have air being pulled in instead of being pushed out....thoughts?

Appreciate your input and guidance.

hey guys...
id sure like to be a coolit member with yall and also would really appreciate some input here...
my pump on my boreas is rattling like crazy so im going to replace it with a pump rez combo for easy filling.

http://www.performance-pcs.com/catal...ducts_id=25341

i really would like to get this one cuz it has manual pump ajustments and looks really cool too. the problem is that i dont know if it will work with the TEC.

1) does the tec have enough juice to power this sucker (it says that its 8.6W max and 6-12VDC)

2) i will also need to know if the wires are compatible or maybe i need an adapter (its a 3-pin fan header with tachometer speed signal)

i cant find any specs for the TEC units. ive contacted Coolit to see what they have to say but id sure appreciate some input from yall as well.

heres a cool vid i think youll like, even better look up the lyrics!
YouTube- Broadcast Yourself.thanks so much in advance.

A thermoelectric friend of mine who was getting free stuff from Coolit told me they are 10v tecs... I always thought they were 12v.

I have run them in parallel at 12v and all I can say is they got hot... but they did not fail. That was on an Eliminator with a 175cfm 92 mm Delta fan... worked great on a 775 socket!!!

I'm trying to mod a Boreas right now so it can handle an overclocked i7. The Boreas isn't even as good as a good air cooler or a Domino A.L.C. on an i7. I used to think highly the Coolit TEC stuff... but really... they can't handle the heat load... at least mine can't... maybe there is something wrong with mine???

Anyway on the Boreas ... I'm going wire the tecs in 6 pairs instead of the stock 4 triples... or all in parallel and install 2 250 cfm Delta's... it's way to loud at full power... but the Deltas alone are good for quite bit lower temps and when you turn them down they are just as quiet as any other fan... I don't no why people complain about them... hey have a better CFM/Noise ratio than most fans. I will run it at 12 volts off of a Thermaltake 650w/60 amp gpu power supply that fits in a dual 5.25" bay.

Time for Coolit to upgrade their TEC Coolers!!!

I'm currently running some water cooled TEC Water Chillers... Man they are power hungry but give me 12*c coolant on a 4.6ghz i7. You just need to have a lot of radiators to get rid of the hotside heat of the TEC's... 3 120.3's or 2 120.4's rads seemed to be the sweet spot. Hard to fit in a case... but I'm working on it.

Here are some pics of my "Thermoelectric Madness"

Could you explain the last 2 photos more please ?
Are theses just drilled copper blocks ?

Indeed it would be interesting to know more about those blocks and the TECs used.

Why not just put yourself out the misery and uncertainty find out how many couples they have. I know you have ummed and ahhhed about this for ages. It is possible to count them but the sealant on the edges often prevents you from doing this.
If they were 10v max. units you would not of run them 12v.

Multiply the number of couples by 0.123 and that will give the the max. voltage at hotside temp of 27ºC.

If they have 127, like I expect they have, then they are 15.6v units. Which is what I have said to you previously.

127 couple is the general number for TECs of the sizes we use it might be less particularly if they are special order but I very much doubt it.
