Whats A Good Max Temp

I have been getting all my preset TDP/TDC's setup in throttle stop. I am currently working on a preset for rendering and I was just wondering if I am going to be doing multiple hour renderings what should my max temperature be. Currently I have the TDP/TDC for this present limiting the cpu to only reaching a max temp of 90-92 degrees. I have not dont any major renderings yet just some minor 15min ones to check the temps. Is this to hot for long periods of time?

I have a I7 940xm.

 

What is your system configuration and laptop?
Download Prime 95 (never used) or Everest Ultimate (I use it, there is free trial version to download) to stress CPU and it will show you graphics of temp
I suppose 80+ max degrees will be fine for your extreme version but can't be sure.

 

Yeah I was benchmarking with prime for awhile to see what the processor could do, but now I'm just trying to get throttle stop setup for what I'm mainly using this comp for. Throttle stop also shows the temps as well as CPU-Z so I know how hot its running. I just need to know what temperature is safe to run at for extended periods of time. Also the rendering maybe uses 10% of the GPU's so the temp with the GPU's is not a problem at all.

 

graphics of temp means graphics/schedule/timetable/chart/(and other synonymous or similar words) of temperature of each core, overall CPU and other if you need.

As I said I think 80+ degrees will be fine for throttle stop.

 

What James D said is run Prime 95 on your CPU for an extended period of time with the settings you made in Throttlestop and if it stays stable and no errors,then whatever else you'll be doing won't make it reach those temps and you should be fine.

 

So if prime95 stays stable at 90 degrees for an extended period of time, this will not hurt the cpu? And rendering uses just about 100% cpu from start to finish so its really close to stressing out the cpu as much as prime 95 would.

 

Your Tj max is 100C. Intel provided that turboboost can be switched on only if temperature will be 10 degrees below Tj max. Intel made autothrottling if temp will be higher than 100C. However Intel also said that sensor can show temp +-5 degrees from real temperature one.

So the safest way is to set throttle to 85 degrees.

All info that was given by Intel about 1-st gen I7 mobile CPU is here:

if the CPU can't handle anymore your computer will eighter BSOD or restart.
If you think you get high temps pretty quick i'll advice you to do a repaste,clean your heatsinks free of dust and lift your lappy(with something DVD case/tictac boxes etc) if you don't have a cooler.

 

Thanks James that was some good info. And yeah I have a zalman cooler and I already have new psate as well as pads on in transit.

 

You have to be careful... when you have 100% load across all the cores and push the CPU with throttlestop it will heat up really quickly and if it reaches 100°C the system will power off automatically (and instantly... ).


When the load isn't always 100% you can push the CPU quite hard with throttlestop as it will always cool down again when there's less work to do.

For me 25x multi across all cores works perfectly when gaming for example, but with wPrime it will overheat very quickly.

 

The official thermal shutdown temperature for Intel CPUs is usually 25C beyond TJMax so thermal shutdown is at a core temperature of approximately 125C for most of the Core i Quad Cores and 130C for most of the Dual Cores. If you crank up the turbo TDP and TDC values then your CPU can randomly shut down at any time when fully loaded before you reach that temperature.

Intel says that if your CPU is not thermal throttling, ie. it is running at less than TJMax, then it is running within spec. The higher turbo TDP/TDC values and higher than default turbo multipliers puts you beyond Intel's original design spec. I've also heard about leaving 10C of room before TJMax to help insure that you maintain full turbo boost but I've seen screen shots at 95C and 96C where full turbo boost was still active. Temperature didn't seem to be a turbo boost limiting factor until you hit TJMax or got very close to it.

I think a peak core temperature while rendering of 90C is high but still reasonable. If your CPU is not happy running at that temperature it will let you know, usually by rebooting.



PROCHOT goes active when the CPU hits the TJMax temperature.

 

Ok, thanks a lot for the info unclewebb...

When I did some tests lately my CPU always worked perfectly fine until a core reached 100°C (observed with TS)
All cores were at 25x multi and load was 100% on all 8 threads... must've been a coincidence that it shutdown a 100°C then I guess...

 

Yeah on one of my beginning tests, while I was testing between rendering and prime with my TDP/TDC values, the temperatures rised pretty fast as others have mentioned. On one test I did touch 100 degrees for a max then back down and the process just kept going with no crash. However I stopped the test as fast as I could so I could lower the values. It just makes a big difference in my temps when I raise the voltage in the BIOS. I reached a max OC with 75v so I ended up raising it to the 150v and it made a huge jump in my temps. So I pulled the voltage back down and found my my max stable OC with 75v but as I said earlier it hits max temps of around 90 degrees. I have backed off a little on this now to keep the max temps in the 80's. Also whenever I render I even out the multipliers on the cores to 26 since rendering will use all cores evenly. Iam currently waiting for new thermal paste and pads to arrive in hopes of being able to up the voltage back to 150v and get a little more power out of it while keeping the temps below 90.

 

What would be a good OC temp for the SB cpus/R3 GPUs? Also, does the Dell BIOS in the R3 etc have a setting where the notebook will beep or shutdown automatically or something when it reaches a certain temp? Or is this something we configure through windows? Please advise.

TYIA!

 

Nowadays it's close to impossible to burn a chip. Once you reach the security temperature(way under the temperature the chip will literally fail) your system will eighter BSOD or simply restart.
for the SB processors the Tjunction is 100° C.
For GPUs they can hold 130° C but their security temp is set way below that (i think ~100° C also).

 

Just want to thank all of you for a very informative thread.

 

Bump for response. Never knew what a good temp was to watch out for while OCing or gaming.

 

The chips nowadays are pretty tough, it's almost impossible to kill them because of the heat.

When I push my 920xm and there's a lot of load for a while it can reach mid to high 80s. (Real-life applications, not stress tests like wPrime)

The CPU as well as the GPU will shutdown immediately when they're really becoming too hot. Unclewebbs post above explains this really well.


I recommend trying to keep the GPU temp below 80°C or maybe up to mid 80s when pushed hard.

Higher temps work too, but it may shorten the GPU life having it all the time at high 90s (and you probably don't want such a hot system )


Of course when you want to benchmark you can push the system really to the limit, but for gaming I say try to keep the temps in around the mentioned level.

 

Thanks for this info. I live in SoCal, where summers get typically hot, so it'd be around 95+ indoors. Would the dual-fan cooling systems in computers like the m17xR3 or the 3820TG or the ENVY 14 be able to keep the unit cool enough?

 

95+ is pretty warm and will definitely have an effect on your temps. OCing will still be possible but the temps will raise faster.
Make sure that you always have a good airflow under your system, maybe use a book or similar to make some room between the desk and the laptop.

I guess having a decent notebook cooler will help with such ambient temperatures... I have never tried one though and can't tell you for sure. I have never used any of the systems you mentioned, but Alienware usually has a decent cooling system which will help a lot.


And not to forget, reapplying the thermal paste will always help to lower the temps a couple of degrees. Maybe take a look at the thermal pads of the GPU (if there aren't any add some)
Also make sure your system is dust-free, especially the vents.

 

Does the R3 require a cooler? Do any of the AW laptops require coolers? (Omit m11x in this discussion since it has only 1 fan hole thingy).

 

People will probably razz me for this but I have never had good experiences with coolers. I like to play on the couch and I balance the m17x on one knee between the CPU and the GPU and find that temps stay pretty cool as the vents are completely free. Otherwise a perfectly flat surface is decent.

 

I have a binder or a scrabble box in mind for the bed. Elsewhere, it's gonna be on a desk, or on my tv tray http://ecx.images-amazon.com/images/I/411dL7nCRdL._SL500_AA300_.jpg
