Watercooling controversy

[V3LCR0]

I finally got most of my parts for a water cooling system, and i am having this problem in my head that is driving me crazy for the past couple of days. First of all though i would like to mention the parts i have got so you guys could get a better idea of what i am talking about.

Computer:
Black Silverstone TJ07 with side window case
Q6600 cpu
Dfi X48 mobo
9800GTX video card
PC power and cooling 750W silencer power supply
G Skill DDR2-1000 2X2 ram

Watercooling Parts:
Swiftech MCP-655-B Pump
Swiftech MCW30 chipset waterblock
D-Tek Fusion CPU Waterblock
Masterkleer 1/2" 13 feet of tubing
Swiftech MCR320 QB-K Radiator
EK-150 Reservoir

Here are some links of some current pictures i have taken:

So my question really is, does a 90 degree barb really hurt performance in a water cooling setup? I was looking around a lot and couldn't find a straight answer . To me it would seem logical that a 90 degree barb would restrict flow to the radiator, but at the same time the restriction might be a good thing because of slowing down the warm water coming into the radiator. I don't know if i am wrong or not and please correct me if i am. Here is what i originally wanted to do Pump>radiator>cpu>nb>reservoir. I was thinking of having the pump physically behind the radiator as you can see in some of my pictures where the pump would actually be. I am not sure the best way to put my rig together so i am pretty much stuck as of this point. My buddy argues that having the 90 degree barb on the radiator would decrease the flow a little bit, even though my pump is already pushing enough gallons per minute that it wouldn't exactly matter having a 90 degree barb. I really would like to have a 90 degree barb as a last resort, but i am not sure as of this point if having a 90 degree barb be the solution. If anyone could please give me any info on what i should do, please give me some info. Also if i am a little vague on something please let me know.

I avoid using 90s' if I can, but in some situations there is no getting around it, they must be used. Make your own like these, I use 3/8" fittings and tubing and it works nicely. The longer sweep of the turn as compared to the barbed fittings won't kill the flow rate as much.

Like woodbutcher said, long radius 90's are your best bet.

Can I borrow your rig when you're done putting it together? :evil:

You're loop isn't that long or complex, so one or two 90 degree barbs shouldn't be a problem.

You sure you need them though? I've seen a lot of TJ07 builds that didn't need any 90 degree barbs.

u guys waiting for me to pop in huh?

Yep, that's where I copied mine from. I found you don't need the barbs though, I did a little pressure testing. The blown piece is 7/16" tygon and the other 3/8" clearflex, I didn't add the clamps until about 10-15 lbs, and ran it up to 50, 5 lbs at a time, 10 minutes at each stop. I had it underwater in a bucket checking for leaks.

If your using the angle one of those sides needs to be barbed or braded because the flat surface with tubing will allow it to draw air into your loop.

The elbow which is the inlet is fine. But the outlet can sometimes draw in air.

This is why you need to use some form of seal like silcon or put grooves into it. :T

Thanks guys so much for the replies! i will buy the 90 degree angles by today, a buddy of mine will be coming over friday to see if we could avoid 90's for the TJ07. I don't exactly get the graph from xtremesystems too well actually, could someone elaborate a bit on the comparisons?

the lower the parabola the better the angle is.

copper 90 is the best, while the nylon 90 is the worst.

Thank you aigomorla, i decided to get the Danger Den Delrin 90 degree angle my dad has a lathe machine, and he could probably make me a 90 like the one on xtreme, but he always works ><. Thanks for the help guys, once the rig is done (hopefully this week, with my 19th birthday) i will post pictures

PICS or BAN! lol j/k

yes if your dad has a machine have him make you a 90. Make sure he taps it correct. G1/4 is the theading.

LOL, thanks aigomorla, i will make sure to let him know

Hey guys, I haven't got started on getting the system up yet because i got some questions on my head if you guys could help me answer them. First of all, i finally got a 90 degree that would work, it is made out of nylon and it fits the tubing i have just fine. My question is, i am kind of stuck on exactly where the tubing goes. I have read around and seen that it would go from the pump to the radiator, then the radiator to the cpu, then from the cpu to the north bridge, then from the north bridge to the reservoir, then from the reservoir go back to the pump, then go back to the radiator again? If this is right please let me know, this is pretty much the only part i am confused on, thanks a lot
