(Un)Official Thermalright Ultra-120/Extreme Temps Thread

[Hachi_Roku]

you know intel thermal specification for q6600 is 62c right?

[davexl]

Yes. But this CPU won't have to last more than 2 years, and based on my experiences with dual cores, I am happy to run it at 1.5000v in bios - which droops to about 1.4v under load.

I only run orthos for stability testing, this machine will be running 3D rendering software which runs about 9 degrees cooler than orthos - ie 63C coretemp at 22C ambient.... I'm not worried.

seriously?

because the stock Intel cooler will never manage that...

[Hachi_Roku]

the stock Intel cooler will never manage that...

if it did i would be suprised seeing as the 6600 stock hit 58c for me

the in 2 yrs i will pm you to send it for free to me

as5 spread thinly on both
orthos:
idle: core 0: 46c, core1: 40c
load: core 0: 56c, core1: 55

edit: fans at 7v for tests

still having problems with 120x
after having the same problem as Funky, all bracket legs bent up, (as posted in another thread). i used a vice to flatten them all out and tried another mount trying to rule out that as the cause of my bad temps. i applied as5 the same and tests were done under the same conditions:



with a typical 120x base and a slight concave ihs temps should still be much lower than this. using more as5 lowered temps whitch obviously means there's not good contact. i was planning on lapping the 120x but was going to leave the ihs alone for now. compared to other ppl's results with the same mobo/cpu my results are 10-15c higher. anyone have any insight on this?

Upgraded from a Ultra-120 to the Ultra-120 Extreme.

Oh My God. Dropped 10.0C off my QuadCore load temps.

This thing just loves a hot CPU - the hotter you are the more you save.

Quad Core Q6600 went from 84C (coretemp) to 74C!!

Notes:

Quad Core Q6600 @ 3330Mhz, 1.5000v bios, P5B Deluxe
22.5C degrees ambient.
Fan = 1 x Scythe S-FLEX 120mm SFF21F
Prime95 20 minute run set to 10K, in place FFT

Ultra-120 : Stable at 84C coretemp.

Replaced U-120 with U-120 Extreme, AS5, same fan. 30 minutes later to make sure case warmed up.

Ultra-120 Extreme 74C coretemp, still 22.5C ambient.

Arctic Silver 5 curing time is not a factor here - The Q6600 arrived a day before the U120-Extreme, so both tests were done fresh.

Not a direct comparison, but close. Here are the numbers from one of my Kentsfield rigs:

Q6600 ES @389x9 = 3500 MHz @1.55 Vcore(1.46V actual) loaded with 4 instances of WCG 24/7, cooled by TT120, open rack.

Load temp is 62.5 C(average of 4 cores) with 18 C ambient.

Interesting - How does WCG compare to small FFT orthos?

[Jodiuh]

Anyone care to rank them? I've found TAT, then Orthos Large to be the most stressful. OCCT didn't even heat up the E6400 more than Orthos. Folding doesn't seem to be as stressful either. (max heat wise)

[DDTUNG]

I've never run orthos. Will see if one of the WCGers has a Kentsfield to do a comparison.

It's nice cause it will tell you fairly quickly if you've done something wrong.

Orthos large and small after 1 minute are identical core temps for this E6400 under Tuniq.

[MuttonFlanks]

This heatsink is really something. I'm trying to get 3.6GHz stable (9x400) and at 1.50 vcore my temps are 38 idle 60 load. With the Tuniq I was already into the 70s on load at 1.50 vcore.

finally someone who can compare both h/s

please can you give us more results and details

[deeznuts]

I don't think my temps are all that great. However, when mounting the board in I probably hit the sink a dozen or more times getting it in, getting my PSU in, etc., and slid the damn thing back and forth since it's not solid. Also, noticed that either the sink or the cpu (more likely) is not flat.

Anyway, with a 21c ambient or so, stock QX6700, 1.3v actual, it idles around 31c and hits 59-60c under load, small ffts in prime95, all 4 cores. In coretemp, everything is about 14-15c more. Using a QuadGT, and fan is the medium Scythe S-Flex.

That's the worst thing about the Ultra 120. It's far too easy to disturb it when trying to get it secured to the motherboard.

Just upgraded to the Ultra 120+S-clip a few days ago. With an skt939 X2 4200@2.7ghz / 270x10, vcore of 1.4 in bios ( 1.41 in Speedfan / Everest ) and room temp of 19c, it'll idle around 28-30c and hit 45-47c under load in the Orthos Gromacs test after 20min. This is with an Evercool 120mm / 80cfm fan@100%.

In the recent issue of Maximum PC one of the editors asked Intel which is the correct temperature reading of the Core 2.
"There are two different temperature measurements going on inside a Core 2. Each individual core has its own digital thermal sensor (DTS) that writes a value to a register in the core. The number the DTS reports, however, is not the temperature of the core, it is a value that counts down to zero. When it hits zero, the core should throttle down. It's also intended to be used for controlling fan speeds, not as a direct temperature reference. Core Temp is guessing (incorrectly, according to Intel) what the offset is.
There's also an old-fashioned thermal diode inside the CPU, just off to the side of the two processors, under the lid. Intel says the temperature the diode reports is probably more indicative of the CPU's actual temperature (and it's probably what the BIOS and more OEM motherboard utilities report). Still, that number isn't necessarily correct."

it goes on to say to accurately measure the temp you have to mill a groove in the IHS and put a thermal couple in the exact center of the IHS. so what i got from this is that Core Temp and all the other programs used to report core 0 and core 1 temps are wrong and that tcase (tjunction minus ~15C) is more indicative of actual CPU temp. Hey that only makes me feel better that my CPU idles at 30C and loads at ~50C! ahhaha

[Jodiuh]

Have any of you actually seen the Core 2 throttle? Does it happen right at the Tj?

[davexl]

On my dual core 6600s, which reports 85C Tj, it throttles at exactly 82C core temp.

So a few degrees before.

You're in the 40's when at idle? Wow.... thats surprising. While I don't have the Thermalright Ultra-120 Extreme, my Enzotech Ultra-X 120 @ 3.4ghz idles at 33'c and its a darn warm day out. It's been around 89'f outside today and inside is not any cooler IMO. (no air conditioning). I max out at around 53'c though.

My small Coolermaster case is pretty jam packed with goodies. SLI 8800gts's, two raid arrays, etc.

I'm also running 1.45v right now.

Ya I'm very happy with my Enzotech especially after reading the temps people are getting here with their Utlra120s'. I'm getting 32c at idle warm day and on load never breaks 39c. e6600@3.2 ghz 1.38v not to mention the fan pointing downwards cools of the PWMs and helps circulate some air around this dam hot 680i chipset on my P532-e sli board.

Got my U120x today, pretty damn happy with it...
