My warmer than I was hoping for temps - Page 2

post #11 of 22
Told ya you should have dropped the other rad and gotten a Petra 355 pump....

But I think it would work with your setup if you add another pump and get some higher cfm fans(75+)....

Yeah, my water temps seem to be pretty good, and there's just not that much heat dumping into the coolant. My coolant temps this morning right as it enters the CPU is 23.4C and after it leaves my GPU is 24.4C.
So I don't think it's the rads or fans, the coolant temps are good and only a few C from ambient.

Anyway this is what I'm getting now

Ambient 20C
Coolant temp before CPU 23.4C
Coolant temp after GPU 24.4C

Idle CPU MB 37C
Idle CPU Core (TAT) 43C

Load CPU MB 43C
Load CPU Orthos Blend Core (TAT) Temp 47C

GPU Idle temp 35C
GPU Load Temp 38C

So really the delta's are actually really good, in fact I have yet to see anyone with an 8800 loading at 38C on straight water and CPU load temps are really not that bad either, just the idle temps are higher than I hoped.

I'll let it run for a couple of days to see if the AS just need curing, then I'll check the flow rate and maybe take the blocks apart to make sure I don't have blockage somewhere.

One of those wierd results I guess..

Yeah let that loop settle in for a day or two...Easy to say its hard not to tweak on it... ...

I couldn't resist, I did the flow check.

This is what I was getting

I added about 10' of 1/2" ID 5/8"OD tubing as intake and drainage tubes into two 5 gallon buckets. So all the tests included this extra length of tubing. I took a gallon measuring thermos, filled and marked one gallon increments. One bucket was the intake that I did all my measuring and the other was the outlet. Then I'd start the pump and let in run to the first mark, hit the stop watch, and then 3 gallons later stop.

Setting 5
Pump only 2.1 Gal/min
Entire loop 1.6 Gal/min
Loop minus one radiator 1.6 Gal/min so not really any difference with the extra rad.

I also tried setting 3 on the entire loop and only got .8 gal/min.

So that's it, I guess I'm a bit dissipointed in the pump. The swiftech specs say it's supposed to be good for a maximum of 317 gallons/hour or 5.28 gallons per minute, yet I'm not even getting half that in my test with the pump by itself and some tubing.

Is this a typical flow rate??

MCP655 only good for 2.1 gallons per minute?

FYI
I found this review:
http://www.systemcooling.com/swiftech_mcp655-06.html

Which did some testing and apparently that's probably not out of the normal with the restrictions in place, so maybe it's time for a second pump after all. It does however point out how the MCP655 is quiet a bit better than the MCP350 in all but very very low flow rates.

Yeah we all ready talked about it in the other thread..The max flow is with no restriction the same with the head...When you put it in a loop with restriction its a whole different story...1.5gpm is about average for a D-5...With 1 18W DDC I was getting 1.5gpm in an actual loop...Thats where the higher head rating comes in...Even though the DDC has a lower free flow rating the head or energy it has will move the same amount of coolant in a loop...Or even more in a more restrictive loop...Head is used up in the loop its at its highest right at the out-let of the pump and its 0 when it returns to the inlet of the pump....So the total head is used up in the loop....

Ahhh...good so I'm probably doing ok (average) on flow then. Just not sure if it would be worth adding another pump now, maybe hold off if/when I get another 8800, then I could run one CPU and one GPU loop.

Yeah that sounds like a good idea that would get you your coolest temp's...Your temp's aren't really bad now...

Don't the MCR-rads need really high airflow fans to work well?

(sorry if that was mentioned before, i'm jumping in kinda late on this thread lol)

Actually they are meant for low to medium air flow. All of their charts are based on a 73 cfm delta fan


and their 220 also charts results at 7v and 5v which reduces performance by about 50 watts or so.



In the end I'm happy, I got the extra OC I was looking for and really small deltas with no heat buildup in the loop. Kind of nice running orthos for a while and drop right back down to the starting idle temp within 5 seconds after quitting. Real world gaming almost doesn't even pull it off of idle temps.

I might try to bow the fusion later,but I'm ggod with this for now Seems like my coolant temps are good, so I'm just not pulling the heat out of the core into the coolant as well as I'd like...maybe I've just got a hot headed E6600
