Core2duo with 8800gtx overclocked and very silent?

[niceandsmart]

I think it's a good point (PSU), thanks.
The price difference between the 620 and the 520 is negligible. I thought the 520 is more quiet(?).

 

[Smartazz]

My 8800GTS is extremely quiet, but I suppose you'll want to look at the BFG model of the 8800GTX though.

At no point did I say "don't get that PSU." It'll handle his proposed rig, it's just something to consider.

From http://www.jonnyguru.com/review_details.php?id=28 (hotbox test) - test 3 being approx 385w - with an overclocked e6600 and 8800GTX he'll easily hit 400+.

"This time, I could hear the fan by test 3, and the results of the higher RPM's can be seen by looking at the intake and exhaust temperatures during test 3..."

The 620 will just give you a little more headroom.

He's correct here. But if you already have the 520, no point in getting the higher version if your not going to SLI.

Just trying to save the op some money he doesnt need to spend thats all :]

 

[zagood]

Yeah, I think he's still shopping, if the 520 is in hand though, he won't be unhappy.

[niceandsmart]

I understood that, thanks (I'm still shopping as I need to know exactly what to buy before I buy).
From the review of the Corsair 520W: "This one wasn't as powerful as the last, and was a little noisier and short on a couple cables... but it only costs $119 and that's a heck of a value for the features this power supply has."

About the Magnum: I read it's actually the Seventeam ST-600EAZ or ST-500EAZ(jonnyGURU).
Here is a review:
http://www.sysopt.com/features/coolquiet/article.php/3600266
I think it's a good choice and I'm considering it as well.

Here is a link to an XBOX water cooling solution where I got the idea for the XSPC reservoirs:

Easier to and maybe overall less painful in installing, to get a Koolance LT, Xbox360 version.

I really really think you should consult howard on the mangnum, or Galvanized Yankie. I swear i read somewhere that its not a true 600W.

the corsiar 620 should be the hi end of your psu list, as i dont see why you would need anything stronger. Also its made by seasonic, so there pretty quiet.

So how does the radiator dissipate heat? - it has a large surface area and transfers it too the air exactly like a air cooled setup. Like I said the water is only used to move the heat somewhere else where it can be removed into the air.

Now if I were to submerge the whole PC in a tub of oil and let the oil take the heat off either the radiator, or heatsync on the cpu, then you can make your 10* water comparison.

In your average modern heatsync you have heatpipes and copper, both of which have better heat transfer then water. The reason water is better is NOT that it has magical heat dissipation properties but because it allows you to pump the heat to a location with more space and better airflow where it can be transferred to the air. Read my original answer again as to why this doesn't work so well for a quiet system.

Ummmm my answer to your statement, the Delta Time required to draw the same amount of heat off the CPU from water off the block, to the release of heat from water to metal over the thin piped radiators, NOT CIRCULAR LIKE HEATPIPES, to air.

Delta Time for water is much more smaller. So no your statement doesnt hold, the end product of the heat is disapated by air via raditaor, true, but the heat picked up by water on the CPU block is much faster and more efficient then air/heatpipe alone.

And if your still in denial,
Show me temps on AIR close to these on LOAD for 30 min Both GPU and CPU
Ambient: 57~60F

And then i'll be quiet about how superior water is vs. air. But so far, ive asked this challange to tons of people, no one yet has come forth.

:]

And noise wise if i downclock my fans to about 70% which there at all the time, i cant hear my system from 2 feet away. I can however downclock my fans to minimum and only sacrific about 4-5C off my load temps, and then it would be virtually quiet.

Loop
Loop2
CPU MAX OC

:] I think thats what the OP has in mind. And not a Dinky Passive Silent system that wont get anywhere near these Overclocks.

If you have better sbuckler please POST, im currious to see how well you did.
Well a better statement is, i wanna see a significantly better stepping opty, which i dont think you have get higher then 3.19GHZ OC on air.

Not many Opty's period i can think of that can go this high.

 

[niceandsmart]

Yep. Actually, at first, I tought of a water cooling passive system based on the above XSPC reservoirs.
For example:
My current system (P4, 2.2Ghz) is the 3700BQE with its "silent" (not enough) PSU, two silent fans (Built-in and Nexus, low rpm), passive VGA card and a Zalman 7000 CPU cooler .
It is silent but I wish I can get the new system I'm building to a higher level of silence.
More important is of course that I want overcloked 6600 and a 8800 VGA.

Great pics. The water circuit includes only the CPU and VGA?
One radiator is enough for the overclocked QX6700?

i have 2 rads, however you only need 1.

The pics didnt come off my QX. The board is still in the process of RMA, long story, but im about to sell the entire thing, and wait for the 45nm die to come out.

The Comp i showed you is my Media Center Opty. The parts i have on it currently are:

120x2 BlackICE GTS + 120x1 BlackICE GTS dual radiator system
2 D5 Liang Pumps
Apogee Block <--- going to get replaced with old Storm, or maybe shift over my Dtek.
2 DD Maze4 GPU Blocks <--- ordered 2 EK 7900GT Blocks. They look hella tight.
Swiftech Micro Resivour

You dont need a dual radiator setup. I used it to compensate for the second D5 pump i added onto it for flow rate.

However, i recomended you sticking with air, and getting the EVGA board. Better hardware is a better investment then better cooling.

And yeah my setup is significantly most expensive then moderate AIR cooling, but as i stated, you cant get those temps on air no matter how hard you tried.


And op, that passive system wont work on a computer. It only applies to small things like XBOX. Those heat exchangers are XSPC resivours. There not a great form of heat exchanger. XSPC does have a passive radiator, but they get insanely expensive, ~150+.

Also XSPC is not a good watercooling name brand. I would think of them more as Toys you can addon to a computer to get stock performance at virutal no sound.

 

[niceandsmart]

The radiator is set up instead of the case fan. How do you cool the case (MB mostly)?

Another question which is a little off topic (I posted a thread about it):
Which memory modules do you recommend?
Do I need the special cooling of the Dominators?

if you look at the pictures i linked you to, the radiator is placed right in front of my case. It takes up 6 bays, but its well worth the sacrifice. The air is pulled from the front, and pushed onto my board.

The NB on a NF4 doesnt need to be watercooled, and its actually adviced not to. The NB on my striker, i decided to not watercool because theres no way i can pull all those heat pipes off.

Also, Gabe, the owner of swiftech quotes: the thing can be cooled passively, or with a relative cheap HSF, so no need to waste flow on it.



If your still interested in h2o, get a petratech elite kit with the dtek fuzion block. You'll get all the manuals you require, and a awesome pump to add, with a well built radiator. To be exact, according to marci, owner of thermochill, the radiator offered in that package is a swiftech quiet series, which is second to only to the thermochill PA series.

Link that you dont need to watercool the NB

Radiator Review By Marci


If your still interested in a h2o kit, i can help you further in picking parts, or refering you to a kit with addon blocks if required. But as i have stated, if you dont have the 250-300 to invest in h2o cooling, it might be better to go air with the EVGA 680i, and then step up to water sometime in the future.

 

[niceandsmart]

I'll go with the 680i.
I also am checking the idea of going with the qx6700 (found used for one month for 850$, good price?).
I haven't decided on the cooling yet. My current system is too loud for me (using it in a very silent room; two slow case fans, cpu fan and Antec 350W silent PSU that came with the case as recalled).
I will be happy to get your help on the h2o cooling. Do you think it's possible to get a more quiet system than with the Air cooling? If so, I'll put the 250-300 on the h2o cooling.

btw. I checked about the Magnum. It is 500W PSU not a real 600W as you said. But it is quiet as can be.

Thanks,
Boaz

 

[niceandsmart]

Why are you selling the QX6700?
I tought of buying one instead of the e6600 (I need the new computer these days).
I read there are FSB problems with the Evga 680i + QX6700/Q6600.

In case I go with the QX6700 (which is probably what I'll do in the next few days) I suppose I have to go h20 cooling or the Scyte Ninja might be enough (and silent on low fan speed)?

ive been having too many problems with my QX rig, so im thinkn of selling it to my cousin. The 45nm die's are suposed to come out sometime this year, so i thought i would just use my opty to hold me off until then.

I don't deny it's possible to get better cooling with water, but I bet it's still significantly noisier then air cooling.

As mentioned on on page 1 of this thread I can cool an E6600 @ 3.2 1.4V using air cooling to about 40 degrees with 1 very low noise fan running at 800rpm in a closed case. Now as quiet as you may claim your system is all the assembled fans and pumps will make a lot more noise then 1 fan running at 800rpm.

If the op. wants the highest overclock going then sure go water. Assuming 10 degrees better for a maxed out water cooling system, and 10 degrees translates into about a .1ghz better overclock then with water cooling you'll be running your core 2 about 3% faster.

If the op wants a good overclock in silence, with the added advantages of lower cost and simpler install/maintenance then my system would suit them down to the ground.

*edit* before we go into the "you can only overclock your E6600 to 3.2" discussion - that has more to do with the cpu and the margin I put in for stability (if I ran it as close to the edge as many do around here it would be running at more like 3.4 but I'll sacrifice a little speed for complete stability).

actually most people on water average about 3.6 on a E6600 while people push it on extreme at 4.0ghz at 1.55V

Phase change takes you closer to 4.4ghz+

My QX was happy at 3.8ghz running at 53C on TAT on cores 0 1 and 58C on cores 2 3
on full load. And yea my setup is slightly louder then a 1 fan running at 800rpms.

My cousin who has a DTEK fuzion rig i setup on a E6600 is running at 3.8ghz Orthos stable, and his cores dont break 40C. So your math is still flawed on OC. The E6600's can easily break 3.6ghz on water.

Well most E6600 that i got to play with. Only exception has been 1, where the IHS was messed up. But after i lapped it, the temps were fine at or near that OC.


Also you need more then 1 FAN to cool your board when clocked that high because on intels the mem controler is located on the NB. That means when you OC, the NB gets hot as hell unless you have some air running over it.

And as i have stated, i dont hear anything from more then 2 feet away, and on low 1 feet away. But then again, all my parts arent cheap stuff.

 

[niceandsmart]

As I mentioned, I did have problems with HDs heating in the past so I added a front fan.
Are you sure it's possible to leave the case without any fan??

I don't want to push the overclocking to the max, but if I'll get a water cooling system I don't see any reason why not.
