Liquid Cooling Temps

[stevebarnes15]

What should the average cpu temp be on liquid cooling compared to that of air cooling?

Installed first water system yesterday,and cpu temp is averaging 15-19 idle,and 22-25 on load,is that about right,or should i be putting more into the loop?

On air my idle was around 31,and about 42 on load.

Seems about right but i'm no water cooling expert ~50% temps drops is pretty good to be fair.

Don't forget, you're never going to be able to get temps below the ambient. So if your room is 15C the lowest your temps can be is 15C. I'm no WC expert either, but those temps look pretty sweet.

that assumption is only aimed at DELTA temps

otherwise the food in my fridge would go off - lol

EDIT:

in the temps we are getting in the UK's latest hot weather, i am getting 25-31C idle, and 39C(max) at load, using a coolit vantage [not a proper WC loop]. my current ambient is 15C. my current temp is 33.7C

I don't quite get what you mean. On standard water cooling (which is what we have here) he will not be able to achieve temps lower than the ambient temp in the room where the pc is situated?

Your fridge uses Freon or eqivalent not water...

Also the food in your fridge doesn't give off heat like a CPU your fridge creates a vacuum and cools the air inside it.

hang on... don't jump the gun here

the whole point of moving air through the radiators, uses one of the major laws of fluid dynamics.

moving fluids are colder than their static counterparts, because more energy is lost as more particles collide

therefore:: the air moving through the fans will always be cooler than the static air nearby

the static air is your ambient

to achieve optimum cool temps in a WC loop these criterias must be met:

• a fast flow
  
• a very low fluid viscousity
  
• use of a conductive fluid
  
• the best fluid cooling available

a vacuum lol

the reason why it APPEARS to be like this IS:

the air inside the fridge contracts as it cools, creating slightly less volume (psi)

Situated right next to the window in my living room,highest temp i've gotten so far is 26 after a couple hours of black ops,and ambient room temp is 15 degrees today being quite windy here.

Reason i posted was i was thinking of getting a 240 rad instead of a 120,but would it make much difference?

 

[dugdiamond]

that's really good temps there

push/pull ???

 

[stevebarnes15]

just push,here's a screen just after coming off black ops a few mins ago:

As you can see the temps are decreasing,and usually settle between 15 and 19 when just web browsing etc.

 

[dugdiamond]

ah-ha - i see - not overclocked

your temps should be lower than that @3GHz

my 1055T is @4GHz

you should easily get 4.3+ only a decent true-WC loop

 

[stevebarnes15]

its slightly overclocked at < 3.1,from stock 2.8 but with my current silverline 1333mhz ,i just can't seem to get a stable oc.

Rams running @ 1437 mhz at present i think.

And oh i just noticed the weather for the next 3 days,arghhhhh more rain.lol

 

[dugdiamond]

click my ying's validator mate

it should help you get a decent OC

if you need any help getting it there, PM me

Leave the ram at 1333 (or as close as) and work on the CPU first dude.

 

[marsey99]

what does hwmon or aida64 say your cpu temp is?

amd cores have been known to misread.

 

[stevebarnes15]

Exactly the same temps throughout 5 different softwares.

I have managed to push up to 3.5ghz after much deliberation,but i had to underclock the ram,and bring it up by host clock,it's now running stable at 3.5Ghz ,but if i push it any more ram timings go up and it bsods before windows.

I think once i have some 1600 ram it should go a little better.

3500 score

 

[dugdiamond]

i think you have almost maxxed out with your bus speed there on that mobo.

although... the GA-880GM-UD2H NB won't go past 300 (i think!!)

you could try dropping the multiplier to x12 and trying 300 (for 3.6), but it may need two more steps up on your CPU voltage.

try it - you wont kill the 1055T at that voltage, as it can easily go upto 1.55v

 

[stevebarnes15]

The northbridge don't wanna know after 2000mhz,it'll do for now until i get rest of components though.

to be honest the rig i'm running atm was just a gap fill until i could afford a better system,having just spent a fair whack on water cooling,case,psu, and braiding,it's given me a good base to work off of.

 

[dugdiamond]

ahh - okay - that mobo aint the best for OCing
