high cpu temps?

Last night i noticed my computer (sager NP9170/clevo P170EM) was a little slower than usual. checked temps and saw my CPU was getting up to 101C, i cleaned it out and now it's still running pretty hot (70s to 80s). CPU is the i7-3740QM. Is there a CPU I would benefit upgrading to that would be compatible, or should I just try reapplying the thermal paste, or anything else I can try? I was thinking of upgrading the CPU anyways and this might make me finally do so, but if it's just the temps causing a problem I'd like to try to get those down first.

 

what exactly did you clean out?

best is to do the following:

-remove backplate, remove both GPU and CPU heatsinks
- clean out heatsink fins, remove any dust clogs in there
- remove old thermal paste off heatsinks and CPU / GPU by wiping off with some toilet paper, then remove any residues with isopropanol
- apply some fresh TIM on both CPU and GPU, reinstall heatsinks
- remove both fans including casings, open casings and take the fans off their magnetic coils (basically, just pull out the fans out of their casings), rinse them off with water and make sure to completely dry them off again before reinstalling. also make sure to clean out the fan casings and remove any dust that might have accumulated in there


additional stuff after reinstall:

- raise the back of your machine by using plastic bottle caps, for example, that improves air flow
- make sure that all fan exhausts are not blocked by any objects
- always use ur machine on hard surfaces and NOT soft ones like carpets, bed sheets, etc.

enjoy

PS: iirc the 3740QM is overclockable by 200 Mhz, so maybe you wouldnt need to upgrade your cpu?

 

Just saying tempurature wise, that's not too hot when you lowered it to high 70s to 80s. Laptop parts run much hotter than desktop, and that actually is a fairly normal temp.

 

it depends, if those temps are at idle or light load, then thats still too high

 

The temps I mention are under load, but in comparison my GPU is staying around mid-high 50s with it raising only to 64 maximum.

edit: cpu's now 80s, with 2 of the cores peaking at 88C. does this still seem average for a laptop?

 

depends on the kind of load youre referring to. if thats prime95 or rendering then those are good temps. if thats during regular gaming its a bit high. definitely not dangerous anymore though, anything below 90C is fine for longer periods of time

You can always use something like ThrottleStop to undervolt your CPU, and potentially even underclock it if you're like me and demand having the lowest temps possible at the cost of potentially a tiny bit of performance. If your thermal paste is more than a couple years old, it may be worth repasting as well.

 

Was actually hoping the opposite. it seems to be throttling the game i'm playing, about a month ago i was getting around 50-60 fps, now im getting as low as 5-10. the game is Vindictus, hosting tends to be taxing on the CPU

 

What do you mean you were hoping the opposite? You can undervolt and underclock your CPU as much as you want in ThrottleStop, and with a lower voltage and thus lower temps, you shouldn't have any throttling anymore.

 

mobile ivy bridge can be unvolted?

 

I don't see why not. If you can't undervolt it using ThrottleStop (you should be able to), you could always flash a PremaMod BIOS and undervolt it in the BIOS.

 

You can use ThrottleStop to under volt a 4th Gen Haswell CPU but there is no software available to under volt a 3rd Gen Ivy Bridge mobile CPU.

The maximum safe operating temperature for the 3740QM is 105°C.

At any temperature less than 105°C, the CPU should be running at its full rated speed. It should not be throttling. Some manufacturers have created their own throttling schemes so some laptops will start throttling at temperatures much lower than this. You might be able to fix that problem with ThrottleStop. If you are having problems understanding what your laptop is doing or if you do not know how to setup ThrottleStop, post your questions in the ThrottleStop Guide thread.

 

The only way is if the bios has the option.

 

I meant I was hoping to overclock. I thought undervolting/underclocking would still cause performance issues, even if it isn't throttling, since it has a lower clock speed? And i'm running Premas' bios mod.

 

Not with undervolting. 4GHz @ 1.03V or 4GHz @ 1.02V is the same performance but lower temps with the lower voltage.

 

Well, if you're getting high CPU temps, I don't see why you would want to overclock as with overclocking, you're likely to get even higher temps since overclocking may require higher voltage. Undervolting and running at a lower clock speed may help performance depending on how much throttling you are getting. For example, if you underclock to 2.6 GHz and undervolt maybe -110 mV, you may end up getting better performance than stock clock speeds that throttle down to 2.0 GHz. I'm not saying that's what is happening here, but you should probably look at your clock speeds when it seems like it is throttling in your game. I run my i7 4710MQ @ 2.5 GHz @ -110 mV and I don't feel any noticeable performance loss in games, and I can even record gameplay locally using ShadowPlay or NVENC with OBS, with no noticeable performance loss. Then again, I'm the kind of person who likes making laptops last years and years and I favor lower temperatures over higher performance. Still, you should definitely look into undervolting if your temperatures are still bad after repasting.

 

who the heck underclocks their hardware unless running on battery?

just follow my advice in my previous post, lower your temps and overclock at your heart's content without having to worry about throttling or spending money

I mean, if you're actually hitting 101c on your CPU, I don't think underclocking is out of the question. Intel CPUs and generate a LOT of heat and lots of people underclock in addition to undervolt. My underclocking suggestion is only if all the advice in your post doesn't provide the desired temps for OP and OP still wants lower temps.

 

Usually if your cpu is reaching 101 C then there is some issue with the heatsink rather than needing to underclock.

 

agreed, underclocking would only be a temporary solution so as to buy some time to get replacement parts
