Whats the max OC possible on a 5960x under water + 295x2 watercooling

[steamgamer]

The water and the cpu block are what decide the temp of the cpu. If the water is already at 20c when you're stressing the cpu, adding more radiators will not lower the cpu temp because it can't lower the water lower than room temperature.

What would help would be getting a chiller for the water, or lowering the room temperature

but just say with 4 rads i was at 20 degress room temp at say @5.5ghz provided the chip could do it wouldnt adding 4 more rads allow me to stay 20 degrees but again provided the chip could do it get to 6ghz or 6.6?

No, the radiators are completely irrelevant, the only thing that matters is the water temperature essentially.

What cools the water down is the radiators, and they cannot lower the water to below room temperature.

 

So, if the water is ALREADY at room temperature of 20 degrees celsius, there is nothing you can do to lower the temperature of the water without using a water chiller in the loop.

 

You can add 5000000000000000000 radiators into the loop, but if it only takes one 480mm radiator to cool the water to 20 C, then those extra radiators will not help whatsoever as you can't get the water under room temperature without a chiller.

 

 

 

You'll be lucky to get around ~5 Ghz with a 5960x in a custom loop most likely.  It will take dry ice or LN2 to get more than that.

ok i see now thank you for your response i think if i do end up building this i will use 2x480s in the roof a an sth10 for the dpu,mob and ram, then use 1x480, 1x240 and 1x360 for the dual 295x2s. do you know with thoses radiator choices on a rampage v extreme what o would be able to expect would at least get 4.5 out of the cpu and 1300mhz on the cpu cores? i know its sort of a lottery but Linus says that 4ghz on a 5930k is very moderate so shurly theirs a number thats 90% guarenteed for a 5960x cheers

@airdeano should be able to do the math for you, he knows all the math behind how much heat one individual radiator can get rid of, and how that will effect water temps etc.

 

I think 1x 480 that's 45 or 60mm thick "should" be able to handle the 5960x at 4.5-5 ghz without any issues (although running at 5 ghz 24/7 would most likely kill the chip in a hurry, it will most likely need 1.5v if it even does 5 ghz that is.)  Then 1 480mm radiator + 360mm radiator would be fine for the 295x2 crossfire with loads of headroom.

 

You'd have massive room for overvolting and overclocking, and lots of headroom in terms of fan speeds, when not hardcore overclocking you'd be able to run the fans nearly turned off, which would result in silent gaming.

Just for reference:

 

I had a 3930k + 2 780's that I ran with 2 480mm 60mm thick radiators for around 6 months.

 

Temps were 40-50C for the GPU's at 1.325 volts @ 1320 mhz + 7600 mhz on memory, and the CPU temps were 60-70C while gaming with the CPU at 1.435 volts @ 4.8 ghz.

 

All of that was done with fans at 600-1000 RPM as well.  Watercooling truly is amazing

thank you again for your response i think iv made up my mind about this rig i now realise that 8x 560s 80mm think plus 5x 480s 80mm think is stupid plus with the pedastools and the 150mm top extension the case would be larger than my fridge, i think i will now go for a 480 monsta [thats all i can buy in terms of 480mm rads at the store i go to] in the roof of an sth10 also in the roof i will have on of the seasonic 1200s, in the basement i will have another 480 monsta with the hdd plex bay and the 360 in the front, in basement with 480 ill probably go with a second 1200 seasonic or if i can find one a 860 or 760 seasonic. the part i dont get is why would i burn out my cpu at 1.5v if im keeping it at room temprature? iv overclocked my dads 4770k to 4.7GHz under a 360mm aio from swiftec at 1.3v and it has been running reasonable cool for 6 months, plus in my cosmos 2 when i had it i had a 3960x at 4.5GHz it had 360x45 plus a 240x80 that it shared with 2x hydro copper 590s and it ran at about 75 degrees in games with the 590s at around 60 or 70 i forget the voltage but yeah im not too sure why it would burn out quick if i kept it cool.

the part i dont get is why would i burn out my cpu at 1.5v if im keeping it at room temprature?

Maybe because too much voltage is bad for your CPU in more than one way (temps)?

this is no major troll i know its insane and i know its overkill i just wanted too see if the watercooling guys new how much overkill this is my friend who works in  little dumpy computer shop said id reach the limit of blocks at dual 560s per block. but i thought well if you added more rads it would reduce the water temp making it possible to oc some more. any way thanks for response im probably going to re plan the rig but i might still go ahead my same friend how told me about the 560s said it would be an awesome project but its stupid but we will see. 

 

The reason more rads won't help past a certain point is because after you have enough rads to dissipate the max TDP of the components, the water in the loop can only be cooled down to the ambient temperature of the air that is being used to dissipate the heat.

 

A 360 Alphacool UT60 can dissipate about 210W of heat with fans at 1400 RPM. If the component puts out say 180W at full load, you have enough headroom so all the heat can be removed from the component. However, since the water flowing through the radiator is been cooled by the air in the room you can't get the water colder than the air in the room. 

 

Adding more rads after the max TDP of heat is dissipated only enables you to run your fans at lower rpm while getting the same temps. 

 

As for the CPU, like all other things it has a certain limit in terms of voltage within which it can safely operate.

 

Here's a different example, say you're standing on a pane of glass 100 meters in the air and you weigh exactly 80kgs. Now imagine if the pane of glass is rated to handle 80kgs of weight for 5 days before it gives out and shatters. Now imagine there are other factors too, for example you can only go 3 days without water. Even if you have a way of getting all the water you need, the pane of glass is still going to shatter in 5 days. At which point you'd still fall to your death.

 

To relate this back to CPU's, even if you can keep the CPU at 20 degrees under full load at say 1.8V, if the CPU itself can only handle V1.5 (heat not being the only factor) it would still brick/die/explode/just not work. If you reach 5.5GHz under not too crazy voltages you'll be fine of course.

 

A 480 Monsta should be able to dissipate between 300W and 350W with fans at 1400 RPM. So one if more than enough for the CPU.

 

Two 480 Monsta for the dual 295X2's would be fine. You don't need to have em chilled to ambient temp.

Instead of buying all those rads buy a freezer and put the cpu inside, GG

If you are not trolling, you are trolling.

I've refrained from saying anything in this thread from the sheer lunacy, but since you persist;

Average OC's on the 5960X are 4.3-4.6, I have yet to see a validated OC above 4.6 that was stable at a long term voltage (1.3v or below). Not saying that there isn't some golden chip out there, but it is extremely unlikely you'll hit anything over 4.6 at any voltage less than ~1.38v. In that situation the temp of the CPU is completely irrelevant, you're going to blow the chip, the board, or both. You'll be pulling ~340w+ (minimum) under load. To have a concern about temp is pointless, you can fry a chip north of 1.4v regardless of temperature.

 

My 5960X and every 5960X I've seen on this forum, or any other, has not been OC limited by temp (under water). It is always down to how much people are willing to risk going into 1.3v+ territory. Sure, if you're insane enough to risk a $1000 CPU @ 1.38v you might see 90C, hell you may even get thermal throttled at 100C, but those are the least of your concerns.

 

For reference, I've had mine at 1.345v (briefly) and loaded w/XTU I saw a max temp of 84C with only 2 240x45mm rads (and 2 GPU's in the loop).

 

If you really want to go insane with this build it would make more sense to run a single 480mm on the CPU and buy a lot of 10 5960X's so you can hot swap them as you fry them trying to push for 4.7. Maybe you'll get lucky.
