V12 kit

[bulldog147]

I was thinking of doing this custom water for my cpu only. Intel i7 2700k @ 5GHz @ 1.38v but I just wondering will this V12 will kept my 5GHz temp below 65C 24/7 compare to my air cooler which it hit 75C (too hot)

Does anyone own V12 and can ocuk test this with i7 2700K and what the temp are like ?

Will be fine

I had a 2600K under similar WC parts, the most I could push out of it was around 60c and that was at 5.3ghz/1.48v, my 24/7 clocks of 4.8ghz/1.32v rarely spiked above 50c

 

[bulldog147]

^^^ 60C at 5.3GHz @ 1.48v sound pretty good with this v12. Was the pump quieter or bit nosey side ?

 

[pgi947]

It depends on the case its going in, I had a separate res but the same pump, I also had a 1080 radiator and 2 GPU's in the loop but the 360 should have the same cooling potential with the fans OcUK provide in the V12 kit

You should get higher clocks at less volts then me if you've managed to squeeze 5ghz @ 1.38v with your 2700K, I needed 1.41v for 5ghz iirc.

 

[bulldog147]

Mine is
4.4 @ 1.27v @ 62C
4.6 @ 1.29v @ 67C
4.8 @ 1.33v @ 70C
5.0 @ 1.38v @ 75C all these with silver arrow air cooler with dual 140mm fans with Antec 1200 (no fans, no covers - just plan metal open air)

Never try more than 5.0 yet because it far too hot

 

[pgi947]

Well you'll easily break 5ghz with the V12 kit

I hope so! because 5GHz @ 75C with 26C room temp (cos of central heating on)

What about the 360 3 x fans is like from ocuk ? Hope it quieter like the silver arrow 140mm quieter fans as I don't like very noisey pump or fans.

 

[pgi947]

The fans aren't the loudest, but they aren't the quietest either, BUT they are the best for use on radiators

As for the pump being loud, that seems to depend on the case you have, some have reported the bay res/pump combo giving off loud vibrations in some cases (HAFX). If it is loud its nothing some rubber washers wouldn't sort, or you could opt to DIY a kit and have a pump separate from the res.

thanks pgi947 for tips and advise

Would you mind if I just do a mini-hijack here? I was looking for 5ghz on my 3770k, would the V12 also be suitable for this? I know Ivybridge tends to run hotter...

 

[pgi947]

It really depends on your chip and what vcore you need to hit 5ghz with a 3770k, 4.8ghz might be a more conservative clock to aim for.

 

[chrisoverson]

Thanks . Would a de-lidded 3770k go as high as a 2700k?

 

[pgi947]

Again it depends on the chip but with some liquid metal it shouldn't be too far behind sandy in the clocks dept.

Good to know, thanks for that. 5ghz would be a great target to aim for, although I imagine it might help to have multiple rads to get there.

 

[bulldog147]

I manage to get mine 4.9GHz last night @ 1.356v @ 73C with intel burn test with a maximum 10x. I guess I got a great i7 2700k chip from ocuk last year (binned chip) but temp never go over 63C while playing games, so, a V12 would be great bonus and push 5.5GHz if I can !

 

[pgi947]

Yep, use something like superpi or 3dmark for testing your cpu at those speeds, heavy prime/ibt runs are going to give unrealistic temps.

 

[bulldog147]

ok I will do superpi at what setting do I need 16K to 32M ?

 

[pgi947]

32m should give it a good workout for 7-10mins, with 3dmark 11 just loop the physics test.

It doesn't hurt to use ibt to find instabilities, just don't do what some maniacs do and max it out for 50 runs, 5 is more than enough to sniff out any oc issues.
