CPU heats ups
MacBook Air 13 running Mac OS X Lion, Version 10.7.5, purchased Sept. 7,
2011.
After
today’s update of Logos 5 Gold, every time I use Logos the fan starts running at
full speed.
The IStat
Pro widget shows CPU usage at 77% and CPU temp at 94 C when Logos 5 is running.
The
Activity Monitor shows that the LogosIndexer is using up to 348% of the CPU (how
is that possible?) and the LogosIndexer keeps running after I quit Logos 5. The only way to
stop it is to restart the computer.
No problems with the same program on my PC running Windows 7 Home Premium.
What’s
up?

Hi Ralph,
It seems, from the information you provide, that Logos is still indexing (if so, you will see the blue icon in the top right hand corner of the screen). Please let us know if you cannot see the icon (i.e. if you believe that Logos is not indexing).
I think that I have the same version of the MBA (I purchased mine January 2012). I find that, when indexing, the MBA runs hot. It is, in fact the only time the MBA does run hot.
The good news is that if all you have done is update L5 (rather than upgrade to L5), the indexing should not take too long.
If you shut down the MBA, the indexing will restart from the beginning. If you are concerned about the heat, I would leave the MBA in a well ventilated spot, charging, until indexing has completed.
Blessings

So much so, that some computers that are able to handle every thing else thrown at them, might then "show" or reveal weaknesses in hardware etc due to the extremely heavy load placed by indexing.
If allowed, Indexing will use all cores, and at a high level.
These results that you are seeing are therefore not out of the question--BUT if this heat inhibits the working of the computer you may need to make sure that your vents are clean of dust or even upgrade cooling fans (hard to do on laptop?). Also it might be best, if possible, not to have any other software apps running while indexing is taking place.

I did upgrade to Logos 5 a week ago but used it mostly on my PC. I guess I had not run it on my MBA until yesterday.
This morning I put the MBA out in the garage where the temp is just above freezing and let it index to its heart's content. I checked at a half hour and it was still going but CPU temp was 82 C (instead of in the 90's). I checked at an hour and it was done indexing and CPU temp was around 40 C.
I can now run Logos 5 with no excessive fan noise and CPU temp and usage are in normal range. Problem solved, I hope.
Thanks, Ralph

I had a similar problem a while back with my previous PC - when indexing, my CPU would overheat to the point of the computer shutting off. I had to take the cover off and put a fan on it in order to complete the indexing. My problem ended up being the CPU fan not being seated properly on the CPU - which led to me building a new PC... Yes, the indexing process uses a lot of resources and stresses the CPU, so make sure all of your cooling vents are clear. (Don't put your laptop on the bed or on a pillow where it won't have proper air flow - my family has a hard time understanding this sometimes...)

Sometimes my PC fan runs real hard in Logos 5 when I have a note document open in a tab. If I close the not tab or move it then the problem goes away.

I have a an HP Pavillion laptop and when it gets hot anywhere like that I get the cheep chill pad with one or two fans in it, I use for just such occurances. Plug it in put the laptop over it and keep the hotspot of my laptop over it, however the usse of a cold garage is a great idea if sticky fingers aren't around!

Well - sticky fingers or light fingers. What a horrifying thought to go out into the garage and see if there has been a meltdown or not, and no laptop - only a hubcab left in the garage. One would want to leave the garage door locked unless the computer is spewing out too much fumes. :-)

Hi,
The reason LogosIndexer is recorded as using more than 100% is because it is using more than one processor core. Your Macbook Air has a dual core processor with hyper threading, thus giving it the equivalent of four logical processor cores. So the number could be potentially as high as 400% (100% times 4).
I just got a Macbook Pro Retina 13" i7 2.90GHz (my first Mac) and when I installed Logos the Indexer pushed the system the same way you described (using ~300% CPU and putting the temperature of each core at around 95C; occasionally one of the cores would hit as high as 101C). According to Intel the maximum processor temperature for this particular model is 105C.

Logos should warn Mac lap top users that when they load a new program they should do it in a cool (low temp) environment. Or maybe they already do and I missed the memo.

PC's are not under as much stress as I rarely see more than 50% when indexing[H]

One users answer to the problem was to put it in the refrigerator. Not recommended.

I agree Dave. My laptop is an older dual-core Acer that tends to run fairly warm even under normal conditions. When I upgraded it to Logos 5 it handled the install and subsequent indexing without getting much hotter than with normal daily use. I never saw the CPU usage go higher than 45%.
