Heat Problem

[ItsMinJunLol]

Hi! Is it normal for my mac to overclock to 2.5 ghz and heat up to 100C? At times, my mac would get very hot even though I don't do anything, and it will continue for about 10 mins and go off. I recently downloaded the Intel power house gadget, so I saw that it boosted to 2.5 ghz while the thermals went up to 100C. I'm pretty sure this isn't normal, and it should be a problem. Also, I noticed that it kinda underclocks? At normal, 4 chrome tabs open with itunes and skype, it was at 1.3 ghz. I believe the base clock of this mac's cpu (i5-5250u) is 1.6 ghz, so does this mean it underclocked itself? Thanks!

 

P. S. Please let me know if any other mac users have this problem too.

at those temps turbo boost should stop and the CPU should thermal throttle BUT only if it hits 105°C first

It hit 101.3C until it 'gave up' and started to go down but it hovered around 100C for approx 10 mins. That's what worries me. It will probs damage components.

100C is very hot, but laptops run very hot in general. it's not a huge risk to the chip itself.

 

According to intel, the i5-5250u has a boost clock of 2.7Ghz, which means it will go up to 2.7Ghz if it can. it will never go above 100C AFAIK.

CPUs slow themselves down (underclocking in a way) when they're not being used, to save power which is very important on a laptop. it's totally normal and functioning properly

Not really, while that is very hot, it depends on how often it happens, but everyone knows macs are not really built to last anymore, and higher temps are par for the course. Remember the old macbooks how their AMD GPU's would die after a few years from heat.....

100c is way to hot , id suggest cleaning out the exhausts ,

granted this is a mac and as we have seen w/ the 5k mac they prefer to toast your cpu/gpu over changing there design just a little bit

 

but this is unacceptable

Woah there... Macs aren't the only laptop that run hot, and while 100C is pretty damn toasty, other laptops run this hot as well. I would suggest altering the fan curve, because apple emphasizes elegance in their products, which sometimes means they slow down the fans, even at 100C

My mum as a pretty bad Ivy bridge i5 thin n' light, and while I had to redo the thermal paste because after 4 years it done bite the dust, 70°C for a thin n' light from the time isn't bad, sure it sounds barely audible, but it does a much better job than the macbooks of the time. Most laptops however do do a better job. Mac failure rates when the average laptop chip ran 10-20 watts higher than now tell that story.

I agree that with a dual core chip the MacBook shouldn't be running that hot, but all i'm saying is that 100c isn't a temperature that will instantly kill all hardware, and that even if the temps are 100c, it's not because apple want their laptops to die. (infact, macs age very well)

 

I know it's not a fair comparison to pit a quad core against a dual core, but the Razer blade 14 runs in the 90s under load even with razer's super loud & highspeed fans. does this mean that razer wants their laptops to have a short life, of course not! it's just a side affect of making thin laptops with lots of power inside.

I would personally not buy, or make, a thin and light with that much power, at the very least I'd have two low noise fans, because two low RPM silent fans cool better than 1 noisy fan. Yes, the Razerblades run hot, but they have significantly higher TDP chips. My old ROG G750 JM kept it's chip at 65°C while not being all that loud, but the fan on that was for a laptop a monster.
