Laptop cooling issues

Thought I would ask about a few issues I had with a laptop I am working with. 

This notebook is always hot to the touch around the left palm rest. Just warm I guess, not blazing hot. CPU is located under the keyboard towards the top on the left side. 

The CPU is a Intel Core i3 dual core CPU with hyper threading, 2.4 GHz and speedstep.

I have a program that monitors the CPU temp. It runs around 126F when idle. If I open over 4 tabs in Google Chrome then run a few other programs like iTunes and Windows Explorer the temp goes to as high as 180F.

Should I worry?

What can I do? I've already blown out the machine with compressed air.

The Notebook is a HP G72 B60US.

Thanks guys.

If you get this while doing non intensive windows tasks, I would first contact the manufacturer about the problem.  It's not uncommon for a laptop to have had a silent recall on warranty work for this type of issue.

1-800-HP-INVENT

If this were an older laptop, I would do a complete teardown of the unit to reseat/regrease the CPU and ensure that there isn't any blockage at the cooling vents/fan.  Excessive dirt often cannot be cleaned out just using canned air.  This is NOT recommended for the home novice.

Yeah I'm not a novice. Thought about tearing the notebook down. Fan seems to be running just fine. I wonder if I need to add new thermal paste. Any other thoughts?

paste might help, BUT if the comp is in a dusty environment then definitely try a clean of the heat exchanger, the worst that can happen is no improvement unless you do a dis-assemble of the comp, then the worst is no work, and the best is a decrease of operating temps, and I also think that the temps are a BIT high for a lappie, and my guess for the palm rest heat would be the hard drive.

Here is a shot of the system temps. Anyone know if this is normal or if this model has issues?

Those are normal temps.  Idle temps around 50-60C are decent operating conditions.  Put it under load and see how it does.

 

Typically, the working temp range on Intel chipsets ends at 100C(at which temperatures, cpu's should last a decade plus).  If you're busting 200F in an air conditioned environment with the laptop positioned for full ventilation access, it's time to do some corrective work and clean that sucker out.  180F under load is a pretty typical result for a laptop.  That said, four tabs in chrome and a music player doesn't seem like it should count as under load.  I call that idle.

 

You may have other problems, spyware, etcetera.  Your system is about a third the speed of mine, but that should still be pretty damn near idle.  I've got a lot more than that running right now and I'm running at 0-3% on the cpu front.

If you've had the laptop for a while, say a year or more, it is probably a good idea to clean out the fans (cracking open the laptop). You should not need to worry about re-applying paste, in fact you should not be removing the cpu heatsink at all.

But before that, how long has the laptop been in use and do you still have warranty?

From my experience all HP laptops do this when the cpu is loaded. I went through 3 different models of HP laptops all with the same heat problem. My last one the fan would run constantly and programs would run real slow. It would get so hot it would shut down I couldn't start it up again until it cooled down. Recently I bought a Toshiba Satellite it is so quite and after hours of use it's still cool to the touch.

I know this doesn't help but always using HP laptops to me it seems like a common thing.

This is on a fresh install of Windows. I am running Avast AV, Dropbox, iTunes, Firefox with 9 tabs open. The system is staying around 135F. Don't want this thing to melt.

Why not write to support at HP...or maybe they have something in their Forums? 

On the lighter side, until you have an answer...

135F with that much open is no big deal, just normal.  If you were doing 180F with that much running, you'd have either a major cooling problem, or massive infection that was leading to high usage even when basically idle.

I previously had a HP laptop i3 340m also, same heating problem would run ~100ºC in a normal room conditions. It's not uncommon so if you're still under warranty get something done about it. Otherwise as others suggested making sure fans/ducts are clear of dust. I wouldn't reapply any new paste. Also invest in a good laptop cooling pad. I would recommend the coolermaster u3. I bought this for £25 earlier this year and saw dramatic drops in temperature of around 10ºC which was a pretty big improvement compared to several others I bought prior and managing only a few degrees drop in temperature. I like the fact you can relocate each fan on the cooling pad rather than having it be static it allows to reposition each fan for optimal cooling.

Still working on this machine. One of the USB ports is really loose. Not so loose that I can't use it, but pretty loose. Is there any easy fixes?

You know I was looking for some serious help. Guess I should have known better.

Quoting kona0197,

Well come on, to be fair Kona you did say "is there any easy fixes"?  'Easy fixing' isn't usually synonymous with 'properly fixed' etc.

Having said that.  ALL fixing begins with examination.  Why is your USB port loose?  Well the answer (even from a topical perspective) would be infinitely easier for you (since you actually have possession of the thing) to determine than any one of us.  Can we provide you with tips as to how you might go about resolving the issue once you have detailed it to us?  Maybe, maybe not.  But doing some of your own further examination is most certainly the correct next step here don't you think?  Especially since you did post this earlier in this thread:

Quoting kona0197,
Yeah I'm not a novice. Thought about tearing the notebook down.

Anyway, if you post back with your 'findings' I'm sure someone will be able to post a more helpful reply!

A loose port could mean bad casing design, poor quality of manufacture, or just that it isn't seated/secured properly inside the casing.  Repeatedly using it could break something, might not, but if it is under warranty you should get it looked at.

Something that I'm not sure has been mentioned yet, laptops usually come with software which optimises your power usage and temperature control.  It could be worth looking at this to see if you're running the optimised plan, which should help keep it cool without unnecessarily draining your battery, or keep it cool actively with the fan when you're using AC power.

Kona.... the answers were/are as 'serious' as the 'serious' issue you have with a loose USB port.

If it's loose - tighten it.

It's NOT 'rocket surgery' ....

A Damaged USB Port can be resolved in a number of ways, but it comes down to how that USB port was designed into the unit.

Answers
1. USB is Soldered and part of the system board; Replace the system board.  Not Cheap or Easy (for non-techie)
2. USB is on a daughter board (smaller circuit board that is separate from the system board.  Cheap, but requires disassembling the laptop
3. Damaged USB Port is just one of many USB ports available.  Cover with Electrical Tape so it doesn't get used.  Cheap and Easy.

If you just are just browsing, then let the CPU run in power-saving mode.
