I ordered a laptop, which should arrive Monday. In the past I've had overheating issues with laptops so I purchased a cooling pad for this one already, but I also plan to run it through Prime95 as soon as it arrives to ensure it stays cool enough when under a heavy load since I don't want to have components die from gradual heat-related damage shortly after the warranty expires.

What temps would generally be considered "okay" as a result of prime95?

Also curious what idle temps would generally be considered acceptable.

you should maybe mention the laptop or provide a link to it so that we know what you are dealing with. I get that you want to find out if it can handle life, but trying to boil it out of the box seems a bit extreme.

Laptop in question is: http://www.toshibadirect.com/td/b2c/cdetland.to?poid=2000098978

I figured Prime95 day 1 was probably a good way to test its cooling capabilities since it should surpass any heat generated by gaming, so if it can handle Prime95 it should be good to go for most anything else.

Why would you run prime 95 on a laptop? Nothing you do is ever going to compare with that load.

http://ark.intel.com/products/75117

CPU is safe up to 100C so keep it under that.

I'm aware Intel rates it at 100 C, but that's not at all the same.

At 100 C it will shut down to avoid being fried, that doesn't mean that 95 C for example would be "just fine" or "Acceptable".

99 C won't do enough immediate damage to fry it, but it will definitely massively shorten the lifespan of the components.

What I was asking was what generally is considered to be an "acceptable" temperature range for long-term usage, not, what does Intel say is the absolute highest the chip can withstand for a short period of time.

Why would you run prime 95 on a laptop? Nothing you do is ever going to compare with that load.
That's exactly why I plan to run Prime95, if it can stay at reasonable temps during 95 it should be fine for all other uses.

Nope it's rated to 100C before it starts to thermally throttle which means until it hits 100C it is just fine. It is not going to fry otherwise the throttling point would be set lower. There is still no reason to run P95 on your laptop it is a waste. More than likely it will throttle most laptops cannot handle that kind of load so enjoy weakening the CPU and all of the components that supply power to the CPU.

I have a 3 year old laptop with cooling issues that shuts off the moment it hits 100 C. It's processor is also rated by Intel as capable up to 100 C.
Clean the heatsink and move on. Add three years to your current one without cleaning it and changing the TIM and the same will happen.

How does running P95 potentially weaken the cpu? It should put it under a full load, but I fail to see how that'd do long-term damage, if as you say thermal throttling kicks in at 100 C, that'd still be the case when running P95.

No, it's literally the second it hits 100 C. It's not a coincidence that at that exact temperature is when it turns off. Your suggestions might stop it from reaching 100 C, but that wasn't the point.

Might not need prime 95 to hit high temps most likely but that all so depends on how hot it gets were you use it too.

Yeah good plan but what about the other electronics around that area that has to deal with the heat..

If i was going buy another laptop i make sure it had a better one that our current one has and would actually go on ebay and check the parts out see how the unit was put together and if they skimped on the cooler and such..

It is a laptop depending on the CPU running 100% through the PWM section of the board really could weaken it. Constantly popping the max safe temp normally isn't the best plan either, but do as you want it's your laptop.

No, it's literally the second it hits 100 C. It's not a coincidence that at that exact temperature is when it turns off. Your suggestions might stop it from reaching 100 C, but that wasn't the point.
That's nice? Is your new laptop shutting off when you run it or have you not had a chance to neglect caring for it yet?

Yeah good plan but what about the other electronics around that area that has to deal with the heat..
Well the VRM's are rated to higher temps, gold and copper are and the PCB substrate is so what other items are you worried about?

I've never heard of such a thing. Any credible source that backs this up? Processors wouldn't be rated at a certain speed if they weren't intended to actually run at that speed.

No shit, that's why I asked what most would consider an acceptable temperature range despite already knowing that Intel rates the chips at 100 C.

Oh look, an asshole. Just what we all needed - because those totally aren't in ovarabundance.

It doesn't shut off the second it hits 100 C because I "neglected caring for it", it shuts of at 100 C because it considers that to be an unsafe temperature - which is evidence that I obviously shouldn't be happy if the new one were to be peaking out at 90-95 during daily usage irregardless of the fact that it'd be remaining under 100 C.

since laptop is all in one i prefer to get lower working temp.
your processor may ok at 90 degrees but the heat will catch your hdd, your board, keyboard and other
i usually just place my hand to check how hot it is :p

Also curious what idle temps would generally be considered acceptable.
How well a cooling pad works is heavily dependent on a laptop's underside ventilation.That said, general advice would be to use SpeedStep to throttle the CPU if overheating concerns are an issue.

Yeah, my current ASUS has most of its vents on the back rather than the bottom. Cooling pads don't do much for it as such.

I looked around at various reviews before ordering the current cooling pad, and ordered this one because I saw that it was shown in a few benchmarks to reduce temps by as much as 5 C when gaming, and by 2-3 degrees at idle.

I didn't find a picture of the underside, but a laptop of that size is likely to have at the very least semi-decent intake ventilation. Smaller and thinner laptops are the biggest offenders when it comes to lacking underside ventilation. Without good ventilation on the bottom for cool air to get in, cooling pads will only cool a laptop's outside.

I'm personally a bit vary of Toshiba laptops sine a former roommate of mine had one die from overheating about 7 years ago. What were you using your old laptop for that overheating would be a concern? Video encoding? Again, SpeedStep or some other throttling program should ease that.

I'd just run a game or something like that or maybe encode a video for say around 30min. Temperatures should be well established at that point. I would say anything under 95C is fine as long as it has sufficient insulating materials so you don't burn yourself touching it!
