Q6600 temps with Tuniq Tower

[VirtualLarry]

Right now, I have Windows 7 installed, and Coretemp 0.99.4 64-bit, and Prime95 25.9 64-bit installed.

My load temps are 48/48/43/45, at 3Ghz, stock vcore.

Should there be such a large difference between the cores at load?

Now at 50/49/45/47, 3.3Ghz, still stock vcore.

 

[rarebear]

My dual core at idel run 2º different..
One is 34º and the other 36º but under load they stay pretty close..

I have NO IDEA if it matter

 

[COPOHawk]

I also have a Q6600 with a Tuniq Tower.

There can be up to a 10 degree difference between cores (momentarily) before I would start worrying about it.

Mine generally has a 1-2 degree difference at idle...and around 5-6 under full load.

Cores 0 and 1 are the hottest.

HTH

 

[VirtualLarry]

Switched to using OCCT:Linpack 64-bit for testing.

Temps get to 65/65/58/58, 3.3Ghz, 1.2v

70/70/63/63, 3.4Ghz, 1.25v

73/73/67/67, 3.5Ghz, 1.28v

When I select 1.25v in bios, occt and cpu-z read 1.28

 

[yh125d]

the q8200 in a dell at the office here loads at like 50/48/41/40

 

[VirtualLarry]

Riddle me this. I've been testing at 3.6ghz, can't see to get things occt:linpack stable, tried 1.3v (BIOS), and my temps were hitting 80C.

Now I rebooted, and adjusted the vcore after a BSOD, and now the temps, at 1.325v, won't break 56C. Something is clearly broken, temps should be much higher. CPU load is indeed at 100% though.

Now 84/84/79/79, 3.6Ghz, 1.325v (BIOS)

Nevermind, I hit 90C. Is that normal for a Tuniq, at these settings?

I did another run, same settings, and occt:linpack only hit 79C. wtf.

Larry something does not seem right with your Tuniq/Q6600. For the voltage you are using, at that clockspeed, you should maybe be breaking into the low-to-mid 70's at absolute worst.

The delta between cores can be a symptom stemming from any number of diseases. The diseases you have control over eliminating are uneven HSF, uneven IHS, and uneven TIM. The diseases you have no control over include uneven solder connection to the die, inherent power consumption differences between the chips, and simple calibration error between the two DTS's at any temperature below true TJmax.

So, first step is reseat your tuniq. If it doesn't go away and it still bothers you then lap the tuniq and the q6600. If it still doesn't go away then it isn't going to because the cause of the problem is beyond your control.

My B3 QX6700 lapped with lapped tuniq has one set of cores that are nearly 10C higher in temp than the others.

edit: silly question, don't hate me for implying you don't know to check already, but are you sure your tuniq fan is operating? Could be you are looking at temps from an essentially passive-cooled chip if your tuniq fan is not ramping up to 1800+ rpms at full load on the CPU.

Regarding the temperature difference shown between the cores, Real Temp has a Test Sensors option, that can show whether some sensors are stuck. I'm finding myself in this situation, the second core is at 7-10c difference compared to all the other cores and experiences lower increments in temp during load.

I disagree, check out these posts from the other thread I dredged up. Seems like 80C+ on a tuniq @3.6 is normal.

Then you have to deal with heat. After 1.35V or so and 3.4GHz+ the Q6600 gets really hot and will result in a significant temperature delta if you try for 3.6GHz. Without good cooling you can easily hit 80C+ under load (Prime95, Linpack, OCCT etc).

I must warn you that even with water cooling at 100% load I still can pass 70C with ease, I can prime95 and orthos for more than 24hrs but the temps are bloody high and I'm looking to replace my Q6600 with an OC'd E8400 or E8500.
My Q6600 is a B3 ES (Engineering Sample) with a VID of 1.25v.

You'd probably benefit from a better cooler. The Tuniq is a good cooler but it simply can't dissipate heat fast enough beyond certain temps. It just ends up getting saturated by some of these hotter CPUs and the temp delta at the high end is pretty extreme. I dropped load temps at 1.38V and 3.6GHz by 14C switching to a lapped TRUE Black (custom bolt through, inverted X-Clamp and neoprene washer) from 87C to 73C in OCCT/Prime95/Linpack.

I was using a lapped Tuniq with lapped IHS on my Q6600 running 3.1GHz for 5-6 months, temps hit about 60C max in Prime95. When I upgraded to my current mobo, the P45 chipset and cleaner voltages allowed me to stably hit 3.6GHz, but also resulted in much higher temps, like 25C higher under load with the Tuniq (85-87C), so I started looking at various temps and results around the web with Q6600s ~3.6GHz. I consistently found people keeping load temps in the low to mid 70s, but they also had better air coolers like the TRUE or even some of the HDT coolers.

I'll say this though, if you don't want to lap anything and only use the mounting/retention brackets stock, you may not see any difference at all compared to the Tuniq. The Tuniq's mounting mechanism allows for much better mounting pressure as you can just keep tightening it. The TRUE's stock screws bottom out however and I found the stock mounting mechanism to be far too loose even with a neoprene washer under the X-clamp (it shifted around with little effort).

In order to drop temps I ended up using 2" 8/40 screws through the back of the mobo with wingnuts to tighten the X-clamp, which I inverted for additional pressure. Mounting it this way, along with lapping the base resulted in the 14-15C temp drop under load, and I'm not talking 10 mins of load, I'm talking 3-4 hours into Prime95 or OCCT where temps will go up another 4-5C higher than what they were for hours. Its still hot for sure, but now my idle temps are lower than they were before (34-38C) and max load is 72-74C under Prime/OCCT/Linpack. Max gaming temps don't break 60C and that's running the more CPU intensive games out there like GTAIV, Mass Effect, WAR, etc where 2 or more cores are hitting 100% utilization.

 

[COPOHawk]

I have built 4 systems that have the Q6600 and the Tuniq over the last 2 years. The clock ranges from 3.0 to 3.5.

The Tuniq works...the main problem that I found was that the stock mounting thumbscrews suck.

I was able to replace them with 3mm x 30 screws that work great. It allows for a much better clamping force...thereby keeping temps down.

My system at 1.35 volts (bios) and 3.3ghz stays at 60c under full load. Before, it was pretty close to 70c under full load. This is also with Artic Silver 5.

well, maybe your right, idc. I can prime95 all night, and i dont hit my bios thermal shutdown temp, but 15 minutes of occt:linpack is a killer. bios shutdown temp is 85c, linpack gets to 90c core temps, then it shuts down.

what are the pros and con of setting my bios shutdown temp to 90c? i could probably pass linpack 1 hour if i did that.

i'm just trying for 3.6 for e-peen value. 3.5 @ 1.25v is fine for me for daily use.

My idle temps at this voltage are 42/42/36/38, 1.3125v, 3.6ghz. any lower voltage at 3.6 and i get A BSOD FROM OCCT.

ok, well, I got a couple of runs in from OCCT, for an hour, and it passed at 3.6, 1.3125v. Sometimes OCCT:linpack runs up to 90C, and sometimes it peaks at 74C. Hard to figure out why.

Btw, IDC, when you said that I should be loading in the low 70s, was that with Prime95, or OCCT:linpack? Because that would indeed be accurate for prime95 temps on my rig.

I found this ,mentions OCing a Q6600 to 3.6 Ghz on air, and reaching 90C with a Scythe Mugen. This link shows that the Scythe Mugen is only a hair better as an air cooler than the Tuniq Tower. Then again, they were running at 1.432v, and I'm only at 1.33v. My rough estimate is that I should be running possibly 10C cooler just because of the vcore differences.

Edit: Tried prime95 again, I get 73/73/68/68 for temps.

 

[njdevilsfan87]

What I have noticed about these quads is ambient temperature has more an effect than anything. I'm using a not so great Gemini II with some low speed Yates on them, and to reach 3.6GHz it takes 1.35V in the BIOS to run stable. I will range anywhere from 70 minimum to 80C maximum (average across the cores) depending on room temperature. I don't care so much for load temperatures, but the idle temperatures are too high for my liking. I'll hover anywhere from 45-55C idle depending on ambient.

 

[nyker96]

i don't think any software load the cores identically at least you don't get the same number at the same instant in time. My E7200@3.5 runs a few degrees apart at load. I think sometimes the seating of HSF also makes one core slightly warmer/cooler. Nothing to worry about. I would still check the HSF as a precaution but it's not unusual to see some discrepancies.

 

[aka1nas]

The heatspreaders on the Q6600s can really suck sometimes. Even after lapping I will usually break 70C on load with a Tuniq@3.2 or so. If the die has a poor internal connection to the IHS, no amount of lapping is going to help.

 

[Painman]

That doesn't look bad, Larry. I had a Delta of around 7º C between core 0/1 and 2/3 of my Q6600 (along with lousy temps all round) so I lapped the IHS; this improved temps and reduced the delta down to about 3-4º C, but of course it's still there.

These things really bake once you start applying heavy voltage... I discontinued testing @ 3.6 on mine once I saw the load temps jump into the low 70s on water (and this was just small FFT Prime, not Linpack). That's hotter than I wish to run day to day.

 

[dwell]

Core 1 on my Q6600 always runs hotter than others by 2º - 5º. Core 0 is using somewhere near it and Cores 2 - 3 are usually the coolest. Core 1 is a bum and is always the one that dies first when testing new OCs.

It's pretty normal, but no cool (lulz pun).

 

[lavaheadache]

the stock mounting on these things does suck!!!. I just found out that by putting system on it side yields a much lower temp q6600 @3.6 (1.32v) on it's side is about 60 versus 80 standing upright and I couldn't get even get it stable.

That sounds more like the heatpipes are possibly operating more efficiently in that orientation.

that is interesting.... I truly am baffled as to why it happens though. I can run prime for hours with the rig on it's side and stay around 60 degrees. Within 30 seconds of lifting it upright the temps start to rise slowly. After 3-5 minutes temps are in the 80's with cores 0-1 being hotter by 5-7 degrees and soon there after I crash out due to temps. My rig has very good cooling. Antec nine hundred with cables tucked relatively neatly. Thumbscrews are bottomed out and the cooler seems snug. I have a near perfect application of as5. All motherboard screws are in place and firmly fastened. There are no wiggles......

 

[acole1]

Do they have tech support that may be able to answer the question of whether or not the cooler is working properly? Maybe the liquid is not doing what it's supposed to while the case is in the upright position. I would guess they *could* have made a bad one, though unlikely.

also seems very rare.

When I had my tuniq (im now water cooling) i was using 1.485 in bios once (1.42 under load) with the Tuniq on low speed at 3.4 ghz and would barely break 65C

It puzzles me as to why you are getting such insane temps at much less voltage

after water cooling witha Apogee GTZ i hardly go over 50C at 100% load, usually stays in the low 50s at about 78 room temp that day I tested it.

I notice room temp has a big effect on temps when i had the Tuniq, in the morning when it was sub 60 in here, I keep my window almost fully open at night, it would idle in the low low 30s with the Tuniq, after the day went by and it got to mid to high 70F in my room it was up to about low 40s at said voltages ^^^ or sometimes mid 40s. I have a 2º degree difference right now between core 0-1 and core 2-3, core 2-3 always run 2-3º cooler

Are you using the fan which came with the Tuniq (I'm not familiar with the specs of the cooler, was using the sonic tower at the time Tuniqs came out)
I've just replaced 2 1200rpm fans on my TRUE with 1800rpm and 1500rpm ones and was able to up the overclock a notch higher (3.61@1.25v > 3.74@1.275) while keeping load temps at 80C during IBT (3C lower than previous overclock, this is with a closed case)
Might be worth it to see if a faster or more fans can yield better temps. I had 3 120mm fans strapped to my sonic tower in an effort to cool my old q6600 B3 at one stage.

Also seems like you might have issues with OCCT, might be worth just using IBT linpack. That always works consistently for me except for my E2*** series chips (But i've mentioned that before ) Also worth mentioning to get max temps it is good to have at least 4gig of ram, 8gig is even better as each pass continues on for 5 minutes.

Just in comparison with with my old q6600 G0 at 1.4v @3.6ghz I was getting 86-88C core temps using the TRUE with those old 1200rpm fans in Push-Pull config. In reviews the TRUE generally does a bit better than the Tuniq, so 90C might not be that supprising at those speeds.

 

[cubeless]

another thing about the tuniq is that u can't see the dust accumulating in the middle in front of the fan...

i'm basically having the same scenario u r having with a q6700 and a tuniq... pulled out the fan and there was about 25% of the fins occluded by a dust mat...

and both my q6700 and q8200 show big variances in core temps on a regular basis when all are evenly loaded...
