I posted a thread a long while ago wondering why my computer (look at sig) was slowing down so much when playing Twilight Princess (I'm too lazy to look for the thread now). I'm trying to figure out some things about my Realtemp readings. Here is (roughly) what I get in the intro of Twilight Princess:
Load: ~ 63%
98-100C on the first 3 cores (which are the only ones being used by Dolphin with LLE on Thread)
95C on the 4th core (unused)
I get 28-31 FPS during the intro scene, almost always full speed (just to let you know I'm not wondering about speed of game, just my processor).
If I'm correct in my assumption, the Load refers to the amount of processing power used on all 4 cores, so the max Dolphin would theoretically use is 75% with LLE on Thread enabled. So how is it at all OK that my processor hits over 100C when only 2 of the cores hit full load, 1 is only half and 1 is basically unused? I just want to smack everyone at my local Apple store in the face for saying that my processor has no overheating problems.
My settings are from the settings for best speed thread + Open MP + LLE on Thread. Specs in sig.
My questions are:
1. Does load refer, as I thought, to all four cores where each takes up 25%?
2. Is there any possible way a company would allow an obnoxious heating problem in a fully-functional product (i.e. not defective)?
3. Is there an *official* processor stability test I can run that would overheat my processor enough to cause a shutdown, thus allowing me to tell Apple my computer is shutting down and getting hot? (I learned that if you try to tell them technical stuff they just pretend like you don't know anything about computers anyway, so I think I should just act like most customers and be unaware).
I already know other potential DIY solutions (like replace thermal compound), but I have the applecare warranty and I don't want to ruin it.

Because heat doesn't stay in one place. It dissipates across solids and through fluids.
Quote:1. Does load refer, as I thought, to all four cores where each takes up 25%?
Total load, yes.
Each logical core has a load measured using idle cycles vs. working cycles. The total load is then calculated by averaging the load of all of the logical cores.
Quote:2. Is there any possible way a company would allow an obnoxious heating problem in a fully-functional product (i.e. not defective)?
Yes, they do it all the time. Apple is particularly well known for doing this.

Plenty. Just search google for stress testing and cpu stability testing software.
google "prime95" it will tear your cpu up,jk,just watch temps

I understand that, and actually thought of that when writing my comment. A core i7 shouldn't produce enough heat out of 2+1/2 cores to beat any sort of decent cooling system and reach 95-100C for the whole processor. When I said it didn't make sense it was getting hot, I was referring to the idea here.
@mario I don't really know what u r saying, but my plan is to intentionally cause a system shutdown so that I can tell the Apple store "my computer got hot and shutdown," this forcing them to do something about my computer. Even if I don't get anything better out of the change, at least I'll make Apple pay some for giving me a crappy cooling system.
Sorry for typos, I'm typing on mobile
Im gonna see if I can't pull out the money to buy a 3570K + Z77 + cooler for one of the towers I have at home; that way I can just stop running Dolphin on my overheating laptop. I have some decent (but not stellar) gfx cards I could use (one can run StarCraft II at mostly ultra settings 1080p). If I can get the money and still have enough for the Wii U I might just do that and avoid the problem.

They produce a lot of heat. Modern cpus require very good cooling.
Your cooling is clearly inadequate.

That's almost impossible. Modern cpus throttle their voltage and clock rate down when they get too hot to prevent themselves from overheating (in the case of an i7m they are programmed to keep the temps below 100C).
I guess now I understand the Apple strategy then:
Promise 3.2 GHz processor
If user reports heating problems, ask if computer shut down
Since it almost assuredly didnt, the customer will say "it slowed down"
Ask what software caused the problem
Say software is unauthorized by Apple
Genius. Bravo Apple. Bravo.

my response was to the cpu stress test, its worth a try, if you really want to overheat it lol,when i was testing my overclocks on my cpu it would either be an unstable overclock or i think when it reaches a high temperature it would crash.maybe ull get lucky and break it, sorry apple's evil man, goodluck with whatever you do next

Thanks, I'll look into it after I look in my wallet to see if I have $600 (~250-300 for Wii U I'm assuming, and ~300 for 3570K + Z77 + cooler). If I can get the processor and mobo for $260, I should be able to get a good cooler for 40-90 I would think.
lmao-i have those 3 things in my tabs somewhere in browser for future upgrade,here you go...

and 3570k is basically same price everywhere
Just build the desktop this year then save up for a wiiU next year if you really want one. It's not like the wiiU is going to have many games that are worth playing this year.
