is 60c load temp too much for a thuban?

I just got around to installing my 1100T, everything seemed peachy at stock. Idle at 27-28c, 47-48c under load (prime95). Was unstable at 4.0 without adjusting voltage. With voltage at 1.45 it seems to be prime95-ing without any errors or rebooting or anything. However, after checking HWMonitor temps, I'm seeing a max temp of 61c. Seems pretty high but I'm not really familiar with Thubans yet.

What do you think? Is it OK? Or did I screw up installing my 212 EVO on this Thuban? lol

60C is nearly the max but it should be fine since there will be no programs out there that would cause a constant 100% load on all cores like Prime95 would. Unless you run regularly programs that stress every core for a extended period of time, you shouldn't worry too much about it.

You might want to improve the case airflow with more fans if you're not planning to buy a new heatsink. The CM690 should be able to fit in a couple more fans.

What kind of thermal interface did you use? From my experience, 1.45v isn't that much on a Deneb/Thuban with decent cooling.

61c in Prime95 isn't that much, considering it induces quite a lot of stress and heat on the CPU. Maybe you could shave off a degree or two by using some better thermal interface, given you are using the stock one that came with the cooler.

I'm using a X4 960T with a Hyper 212+(HDT base) and under load with 3750 mhz / 2600mhz NB @ 1.3v/1.2v it reaches around 44-45 degrees, probably more under prime or linx. The fan is a Scythe SlipStream 140mm 1700rpm@850 from a fan controller.

I wasn't sure because I read a lot of threads on other forums where people were saying you shouldn't get over 55c. I noticed your NB was 2600 - any reason why? Mine is at 2000 by default and I haven't changed this. I haven't changed any NB voltages either.

When you say "thermal interface" are you talking about thermal paste? If so I just used whatever came with the 212 EVO HSF. I put a pea-sized drop in the middle of CPU.

Yeah, I meant thermal paste. It's decent, but an Arctic Cooling MX-4, MX-2 or Prolimatech PK-1 are far better when it comes to heat transfer.

The reason I overclock my NB also is because RAM read, copy and write is much faster, hence a faster and more responsive system. TBH, just clock speed increase doesn't do much justice to an AMD system. I'd rather have 3750 mhz and a higher NB speed. The performance increase is so much more tangible.

If I recall correctly, Thubans and Denebs have their thermal throttle set at around 73 degrees on the cores. So if the temperature reported by you is 61 degress on the CPU and not the cores, you are in safe zone. Also, the Evo is a disastrous heatsink. The Thermaltake True Spirit is way better when it comes to cooling and High TDP. And at 4 Ghz we are already talking about high TDP for an AMD.

Here is a test between the two.

It only takes 1.375v for my thuban to do 3.8ghz and I never pass 44 to 46c stress testing so your voltage is probably a bit high that's all. I'd definitely roll it back, with any luck you shouldn't need all that juice and if you do I wouldn't suggest pushing those kinds of temps/voltage's.

60c temps are absolutely fine with Thuban. However, the temps given above do look a bit on the high side. What's your ambient temp?

Hmmm. Maybe I should take it all apart and just make sure I really did set up the 212 properly. Ambient temp in my room is about 20c. When not doing much, HWMonitor is reading temps as low as 26c on the cores.

I had a look at that Thermaltake, seems I can't find it anywhere for sale anyhow. Interesting to know it's better than the 212. I always heard the 212 was one of the best in its price range though. I had initially wanted to get a Noctua, but they are usually much more expensive (and I lol'd when I saw how huge the D14 is in a vid hehe).

So is 1.45v a worrisome voltage for this chip? It didn't seem to be stable at 4.0GHz at lower voltage though. I should focus more on OCing the NB speed instead?

NB at 3.0 it won't post. At 2.8 it runs fine, been testing with Prime95 for a bit without anything wrong so far. Max temp so far 53c (but then again, cpu is only at 3.3GHz right now).

I checked NB voltage in the BIOS, and the default setting is already the maximum, is this OK?

212 should be fine the Thuban isn't known for running hot, you just have to remember Thubans throttle up the voltage at full load on their own so whatever you set the voltage to, estimate at least an extra 1v or so is being supplied at full load. At 1.450v you're in the 1.5v range and typically these chips at stock voltage will hit 1.475v at full load so that's not to far off from default. A lot of folks completely forget to account for the fact that thubans have integrated voltage adjustments.

If you're running at 1.450v right now then your temps are going to be a bit higher than mine that much is certain but 50's is good enough, so now you just want to find the sweet spot. Say you can run your chip at 3.8ghz/1.400v or lower, then you know you've reached the limits of your chip and shouldn't bother letting it get hot and overvolting for just 200mhz. I ran an x4 into the ground maxing it out at 1.475v (non-thuban chip) so it's definitely worth taking the time out to see where you can get your chip comfortably stable. Also worth noting I run my computer without a side panel for better airflow so that contributes to the discrepancy.

:hmm: ... Northbridge at 2800??? Seems kinna high I think my box would freeze at that NB setting but my high DDR 3 speeds are not stable past 250mhz nb. My NB takes 1.155v @ 243mhz so if you're running at something like my boards max of 1.3v+ then that would definitely be contributing to higher temps.

I would say CPUs only get too hot when they're actively throttling; AMD isn't going to sell you a CPU that would run hot enough to actually damage itself within the warranty period, it's just not in their best interest.

I would check your case airflow. 62c is way too hot for Thubans since their temps are off by 10c.

You're probably ok, but when I overclock I like a little saftey margin built in. You're right near the limit. And depending on where you live, it might be pretty cool in your home, in summer it could get worse.

I'm at 1.48v and 4.03/2.6GHz, I don't think I've ever seen over 54C.

I'm using HWMonitor for the temps. NB at 2800 was just to see how far I could put it. 3000 wouldn't post, 2800 it seemed fine. Anyhow, regarding the voltage and temps. Consensus is I should keep it under 1.4v and temps below 62c? It seems my chip has a hard time overclocking without more voltage (but the NB was easy).

I might just disassemble and reassemble it all to be sure I didn't screw something up. Recommendations on good thermal paste? Does it make a big difference? Seems like mine is running hotter than it should be, so maybe it's just user error.

Edit: NB at stock 2000, voltage at stock, cpu at 3.5GHz it is priming at max 48c (idle 22c). no errors or crashes after about a half hour of prime. HWMonitor shows cpu vcore as 1.43v under prime load. is that bad?
