I haven't posted in this thread in forever.

The i7 920 rig has changed drastically though:



I've had some more time to mess around with it, so I decided to overclock it on air. My 920 is a C0 chip, so it's not as OC friendly as the D0's. (I've hit 4.6Ghz on water, so we'll see what it can do on air)

I'm currently posting from 4.5GHz



EDIT:

Should be easier to see, then trying to look at the screenshot


It's not prime stable, but it's benchmark stable as well as Fallout New Vegas stable lol!

I'll be pushing it more shortly





Hey guys, girls, and hiigaraan(joke). I've asked for many pics, but have never actually shown you guys any. So do to some recent problems(liquid getting in my PSU) I had to take my rig apart. Here's some pics of putting it back together.

The LGA 1366 socket


The i7 920


Putting on the AS5


DR. MOS


Vigor Monsoon 3 AKA. Not my favorite cooler


6GB's of DDR3


Putting it on the MOBO tray


That 8pin connect that hii hates


4870 number 1


4870 number 2


Crossfire


Sliding in the tray


Wire management


It's alive


Comments?

Water Phase TW0:

I got it to 4585Mhz today, but any further and the BIOS locks up LOL! (Guess it's time for another BIOS update)

I had to clear CMOS, for obvious reasons, so I'll try for 4.6 tomorrow then.


Still, 4.5GHz, not bad for a C0 920 on air cooling.

Seriously. Despite being cheap, it is still far more expensive relative to the cost of distilled water.

That said, the reason distilled water is chosen is likely not due to heat capacity but instead thermal conductivity. Water's thermal conductivity is on average 5 times higher than that of mineral oil, making it much better for actually cooling things.

who knows? maybe the mineral oil used is much more expensive than water. would be worth looking into if youre looking for a liquid cooling solution.

I'm fairly certain that if oil was the better option, it would be more widely used.

I think hiigaran is pointing out that the oil also cools faster than the water, essentially evening it out.

That means it will absorb all the heat it can sooner then water will
thats what i was looking for. thanks.

Why would that be better?

The oils heat capacity is lower. That means it will absorb all the heat it can sooner then water will. When that happens it will stop absorbing heat, meaning heat dissipation will stop. Whereas with water it will be able to absorb more heat.

Both the water and the oil would be cooled in the radiator, so the oil being cooled in the radiator makes no difference.

Water can dissipate more heat, that's why it is used.

hiigaran


but if it heats up faster and is being removed and replaced with cooler oil, wouldnt that make heat dissipation better at the radiator (were still talking about oil in a water cooling systems piping, right?)

(Mineral Oil)1.67 kJ/kg.K vs. (Water)4.18 kJ/kg.K

The mineral oils heat capacity is less so it will heat up faster, and be less efficient at absorbing heat.
