DELL XPS 15z CPU heat Issue

Hi Guys,

I have the above and when i play games the CPU can hit around 94c, is this a standard operation temp or this an issue?

My GPU is around the mid 70's when pushed.

Intel Core i7-2640M 2.80GHz

Thanks

 

All current Intel CPUs are designed to push as hard as possible without going over the temperature limits. If your CPU is that hot and down-stepping below the stated speed, you have a problem. But as long as the temperature isn't affecting your use of the computer, there's not too much to worry about.

 

Ok but what concerns me is that the CPU's maximum operating temp is stated to be 100c.

I'm wondering if Dell have done a crappy paste job like they did on my Alienware.

 

Probably... when I repasted my XPS 15, there was lots of gunk all over the CPU and GPU chips circuits boards, but very little on the actual core/silicon chip itself....

 

It will invariably be worse than if you do it yourself (assuming you do it right too). Though there shouldn't be much on the chip itself, pjcronje, it is just supposed to be a thin layer replacing air between the components.

The CPU is designed this way. It ups the CPU speed via TurboBoost as much as it can (when under load), then as it approaches 100 degrees it throttles back to keep it under 100. And if it still is too hot, it throttles below the base speed. Then if it still can't keep it cool, the CPU shuts down if it hits 100--which is still below where real damage starts happening.

The moral is that as long as the CPU is operating at its stated speed or above, you're doing pretty well. Doing a better paste job will help performance-wise, but it won't get the temperatures down that much simply because the processor was designed to scale its performance as heat allows.

 

I know, that's why I replaced Dell's shoddy mess!

 

all new computer now, has a higher temperature. same the pentium 4 time. may need revolution again for solve this problems.

 

If u are too concerned about it... u can alway turn off turbo boost... that way processor won't go above 2.80GHz which will result in lower temperatures......

Set power plan to balanced---- go to "change plan settings"-------then click "change advanced power settings"
This will open "Power Options".... then slide down and find "Processor Power Management"---- expand it and you will see "Maximum Processor State" ---- change its values from 100% to 99% and click OK.
Now whatever you do , your processor won't clock more than 2.8 and will run cooler....

 

that's because of turbo boost to get as much performance as possible...
if you don't like it , simply turn off your turbo boost as stated above and you will have a cpu more like Core 2 series which will be cooler.....
