quad core temps

[Isriam]

pa120.3 single loop with fuzion nozzled quad core

3825mhz 1.512v loaded small fft's = 66-69c core temp

how many degree's should i drop adding a pa120.2 to the same loop with yate mediums?

[Bail_w]

you wont see any differences even if you add another radiator because a single PA 120.3 can handle a overclocked quad easily. You should try to remount the waterblock again to see if any changes.

[Isriam]

ok here is some more work...

3825mhz, 1.456v, 60-62c max load temp

adding another radiator won't adjust the temps? are you sure? I've reseated 4-5 times and this is the best so far.

[muppenz]

Try touching your radiator with your hand. If it's quite hot, you can tell it's radiator or just needs stronger fans. If it's not that warm to the touch, it's safe to assume it's not the radiator that's lacking. A 120.3 can easily handle a quadcore on it's own. Even with 40cfm fans and 25c ambients it shouldn't reach those temps.

[Eddie3dfx]

Is this a B3 or G0 stepping?
If this is a B3, then your temps are accurate.

[Talonman]

What fans, and TIM used, and current room temp? :)

[disruptfam]

thats defo not a b3

[septim]

other parts of your loop? pump?
where is it mounted? (airflow lacking?)
picture would be nice...

[Eddie3dfx]

why definitely not a b3?

[SiGfever]

why definitely not a b3?

That clock speed at that low of voltage has to be a "GO".

[Eddie3dfx]

Hmm.. yeah, 1.456v is low.
Lowest stability I can get on a b3 is 1.53 at 3520mhz
If he has a G0, then his temps are ridiculously high.

[Isriam]

i've been water cooling for a long time and i've been overclocking for a long time. i think its a pretty simple question ;)

why buy a pa120.3 vs pa120.1? because the pa120.3 has more surface area for cooling, so since i have a spare pa120.2 why couldn't i add it to my loop, and reduce my temps? i'm more curious in the benefit of adding it to my loop. is it going to perform as a pa120.3 + pa120.2 where my delta could be taken from martins spreadsheet and just simply added together, or are there more factors involved?

for those who are curious, system specs as they stand it probably will stay for awhile. i'm having too many crashes any higher.

q6600 g0 L733
1.400v 400 fsb
evga 680i A1 with vdroop pencil mod (1.400 is 1.410 on load)
geil pc-6400 800mhz 4-4-3-9-2T

I can get 3.825 @ 1.450v if I need to, but it kept crashing last night although it passed orthos fine.

[Sideroxylon]

More radiator doesn't equal lower temps always. You're not pushing that 120.3 at all with just the cpu on it. What your experiencing is just the limitations of water cooling. It comes down to how much heat you can transfer from your cpu to your block to your water and how fast that is achieved. It's not a radiator issue.

Assuming you have a good mount, those temps really don't seem bad for the voltage and oc you have on that quad core.

[leo_bsb]

we need more info, CPU block, fans , etc.
FYI I'm getting 51ºC tops with my q6600 100% load @3.6 1.42V and I have a 8800GTS in the same loop using a PA120.3 with low speed YL with hot brazilian ambient temps.
You have a bad mount, low air, bad block, it is not a Radiator problem.

[dnottis]

thats defo not a b3


Sure could be, heres mine....G0, bah!

Lapped b3, in sig.

[leo_bsb]

When you say loaded, what exactly are you using to load your CPU? And how is that SW configured?

andyc

orthos, occt, fah, I tried any torture test available. I run orthos + atitools artifact test at the same time when I was testing stability.
I run FAH 24/7 and the temperatures top 51º changing to 52º occasionally.

just reading these temps, why is it people watercool again? They are only 10 degrees lower than good air and my ambients are 29 degrees.

That 10 degrees makes all the difference to some people, including me. Not to mention the awesome looks and "wow" factor from friends and family.:D

[systemviper]

Also the new pipes with fin, massive air-cooling technology has matured a lot in the last year. I remember building rigs a few years ago and the air cooling mounts were so backwoods, compared to todays.

But i would hope to get at least 50's under stress with water-cooling to make it worth the extra cost. I also got great temps with air on my first rig and had to think hard to decide if i wanted to water-cool or not.

Also it is a ego/bling thing to have a electronic unit cooled by it's arch nemesis water and you can say you designed and installed it....

Also for our hot video cards. Mine ran at 80c now its 45C load.

Peace and quiet as well.

Well, that depends...

[disruptfam]

can some1 link to the prime95 for quad... please... edit : nevamind :) its above

[nzbleach]

but then you go and add gpu's chipsets, mosfets into the loop and pretty much lose any advantage water may have.

what the ambients????

I load @ 62c on my b3 @ 3.2ghz 1.30v 32c ambient...

[pvtdonuts]

I'm running my G0 on a single loop with a pa120.3, dtek fuzion and a D5 and I max out @ 57C when running Small FFT's in prime. Sorry bout the big pic

[disruptfam]

when i loading 62c @ 3.2ghz with my b3 i wish i had a G0....

Ambients are high though...

i can get it 3.4ghz when ambients are a bit lower but still....

Temps stay the same if i had my fans @ low or high so that would suggest my rad is .......able to handle the heat??

whats the max i my cpu can handle under load??? 70c???

[Isriam]

so is adding more surface area to a radiator going to give me a lower delta :)

[septim]

not much +1

(lowering ambient and keeping it low would be much better = aircon room...)

[fireice2]

10c is quite a huge temp diff! :D

would running pure alcohol help in the temps? :D

[Talonman]

snicker...:p:

[leo_bsb]

only 10º??? you should say all that immense vast big and great 10º!!! :yepp:
We all should remember the forum name.

[leo_bsb]

Download Prime 95 v25.5. Set it up to run 8k FFT "in place" only and see what your temps are. They'll go at least 10c higher. Which is why I asked. You have to know exactly how someone tests, and how that test is configured before you can gauge temps.

Just a suggestion,

andyc

I used prime too, same results.
I told you I did all torture tests available. I did prime plus rthdribl_1_2 and atitools at the same time :up:
The max I saw my temperatures go running all at the same time was 55, average for 26 hours was 51.8

[leo_bsb]

ok, suddenly I started to lie :rolleyes:

[nzbleach]

I was just being generous with the 10 degree difference. Seeing people loading at 60 degrees on water when my ambients are 28-30 degrees with my CPU loading at 65 degrees (g0 Q6600) @ 3.6ghz 1.50 vcore on a TRUE it just doesnt seem right? Watercooling seemed to have a much bigger advantage 2 -3 years ago it seems.

[leo_bsb]

Impossible if you had it configurted the way I suggested, big difference. You can't tell me you run FAH at 51c and Prime 95 small 8k "IN PLACE" FFT's and get the same temps. Just can't happen. Not on water anyway.

andyc

maybe you are half right or I am half wrong, looking the 4 cores I got mixed temperatures after prime.

55-57-49-52, ambiente should be 27º today. Is it impossible?
