Adventures in water cooling

On december 24th, I purchase a water cooling system from "COOL IT" brand.

I paid b y credit card and the shipping was 4-5 day.

On the 6th day, I had to contact them, as no water cooling, no phone call, no email.

In responce to my contacting them, my order was changed from pending to doing.

Why was it not that way from the begining.:bash:

So it is now Jan 1st, 2009 8 days later and still nothing.

I must say, this is not a good start to the project.

I will post more as information or the parts come in.

Update:

It is January 4th and still no sign of my product or any email explaining what or why.

I must say, this is a VERY poor showing on CooIt's part.

I wish I could tell you something about their product, but 11 days later, I still have nothing.

Don't know which cooler you ordered, but I just looked at their site and one of their coolers was Out of Stock.

Good luck!

$50 I can overclock further than you on air cooling.

Well,
It's Jan. 7th and nothing has arrived.

There has also been no form of contact from CoolIt.

I will again have to be contacting them.

For anyone considering this product, realize it was ordered on Dec 24th and as of Jan 7th, nothing.

This is a very poor showing on their part.

OK,

January 8th and I get a communication from Coolit.

I is saying it "should" ship on the 8th.

Order taken on December 24th, and they wait till January 8th to "should" ship it???

I call that very poor.

The unit better had be worth all this BS.

Btw,

With a Zalman 9700, my cpu temps are between 28 and 30 with internet chat/reading and music playing.

We shall see how the number compare with H2O.

OK,

January 13 and my water cooling unit has arrived.

Installation took about 1 hour including reading instruction 2X and carefully test fitting before any actual work was done.

Please note, it DOES mater which way the water block (the part that goes on the CPU) is placed.

The 2 tubes need to be closest to the top of the case. (follow instruction exactly).

Please note, I am runing the coolit fan @medium.

It is kinda loud (but not that much louder than the zalman at full bore), but we will do a burn in test and see as well as some testing on high as well as low settings.

Just listening to music and being on ATS i have cpu temps between 16 and 20C.
remember, with my Zalman 9700 i has 28-30C idle temps.

So far I am impressed with the performance of the unit.

I have run orthos...... like prime 95 to stress the cpu.

After running it for 1 hour, the cpu temps were 35C-impressive to say the least.

I will download and run prime 95 to see the results.

So far, so good.

I downloaded prime95 and I am stress testing all 4 cores.

Temp jumped to 39C in 1 min.

7 min in and up to 47C with all 4 cores@100%

I will edit and post all 4 core temps after 1 hour.

Ok,

After over one hour with all four cores @100%, they maxed out @49C.
(using Prime95)

Today, at idle, my temps are 10,10C and 13,13C.
(you see the q6600 quad is really 2 dual-core setups on one processor heat sink).

Today/or tommorrow I will try putting the stock 180MM case exhaust fan on the outside of the case (the water cooling unit is bolted there now) and see if I can get good performance with the fan on low.

The fan is large, slow spinning, so i think this should really reduce fan noise, but @ what performance cost?????





Bye the way, gpu (video card processor) idle temp has gone down to 50C.

I suspect this is due to the fact that there is no ( CPU) heat sink pouring heat into the case, just by the video card.

Going to overclock your processor yet?

Bet you could do 3.4ghz - 4.0ghz with those temps. 3.6ghz maximum unless you overclock your memory ( By virtue of the lowest memory divider being 1/1.)

Prime95 and Orthos are old hat for stress testing, use the hour test with OCCT.

Why do you need it so cool? As long as you're under TJUNCTION, you're fine? That's 70 - 75 degrees on the Q6600 G0, less on the B3 stepping. That's what my Intel Electronic Engineer contacts have told me, and what presentations at CES have shown.

If you want it even cooler, lower the CPU voltage. It's always very high by default. My default is 1.3250 volts, I lowered it to 1.24375 and managed to overclock to 3ghz with the same temperatures as 2.4ghz at 1.3250. Lower it a few notches, run OCCT for an hour. If it doesn't crash, lower it some more, and test that.

In one package.

I have loaded, after a bit of delay, Hellgate london.

I have turned up everything to max.

After about 2 hours of gaming, my cores were between 21 and 23 C (cooling with a Antec 9500, gave "Idle" temps of 28 C for reference).

Lower voltages to get further drop. A Q6600 should run 1.15v at stock speeds, not 1.29 or so as default. And overclock it. Also, use Linpack if you want to stress test something, even better than Orthos, Prime95, and OCCT.

lol @ temperatures. Mine will record 5 degrees hotter than REALTEMP, if that's what you use.

You need to push it to the limits!!! Throttling only occurs at about 20 - 25 degrees from TJ.max. On the Q6600 you can go to 75 - 80 degreecs without probs. Wouldn't want to run that 24/7 obviously.... Linpack is over 10 degrees hotter than Prime95 which is 10 degrees hotter than real applications... so i'm not phased...


I need new cooler though.... hopefully I can get 3.6ghz - 4ghz... LINPACK stable too.
