Title: CPU getting lazy
Post by: bryan1998 on November 17, 2010, 10:19:03 AM
Hi, when i play a game (like need for speed world), my computer goes just fine.  Then it starts lagging, and i see that my cpu rates are going down (80%-95% to 5%-15%), which results in heavy lag!  It happens every other Minute.

SPECS:

Model: ASUS Republic Of Gamers G72GX RBBX05.

CPU: Intel core 2 duo (2.56 GHz)

GPU: NVidia GEforce GTX 260m CUDA 1GB

RAM: 6.00 GB

OS: Windows 7 Ultimate

Can you please post your temperatures using a program the HWMonitor or Speedfan.

How do i do that?

Download and install this: http://www.cpuid.com/softwares/hwmonitor.html (http://www.cpuid.com/softwares/hwmonitor.html).

Run it and it will give you all the temperatures in your system.  Post them here, make sure to tell us if they are in Celsius or Fahrenheit :)

If that doesn't work you could try this program: http://download.cnet.com/SpeedFan/3000-2094_4-10067444.html (http://download.cnet.com/SpeedFan/3000-2094_4-10067444.html)

TEMPS:

GPU: 187F

CORE 1: 135F

CORE 2: 140F

I'm assuming that these are in Fahrenheit.  They do seem a little on the high side, could you also check the temp from while you are playing a game: open hwmonitor, play game for a while and check the maximum temp recorded by hwmonitor.

I'd also check that all the fans in the system are running and are dust free.

GPU: 196F...
This is your problem:  GPU is over 90degC.

Do you really believe that 1.111 degree of "over" is critical? truenorth

How to fix it?  I got a laptop, they say you can't clean out the fans...  Mine's like, almost a year old!  Not that old.  It gets pretty hot though.

I would like to have Co Com respond to my observation --however as a practical matter to the "heat" issue separate fan coolers are available (very inexpensive) that can be placed under the laptop to assist in the cooling. However i would like to hear from CC or others as to whether there is a "heat" issue 1st. truenorth

My fan is in the rear of the laptop, so those "pads" won't help.

Actually, most laptop fans are in the side or back. Those pads are designed to circulate air around the bottom to help dissipate heat from there. It's not meant to work directly with cooling systems already present in a laptop. They're made to provide additional circulation and cooling.

As for those temperatures, 160/167F is beyond Intel's maximum for a Core 2 Duo, which is about 140-145F, but that depends on the processor model. In any case, I'd say this is where your slowdowns are coming from.

No, I just meant it's too hot, not that's it's 1.111 over 90 (which it is); even 80 would seem too hot, but 90 (or if you prefer, 91.111) is on the verge of shutting down.  When it's that hot, not going to argue over 1.111 deg (C or F).
Now that we know it's a laptop, it may just overheat to destruction.  Laptop cooling is marginal, at best.

Do you know where cool air enters & where hot air exhausts via the fan?  If you can peer inside and see a lot of dust, you will have to open the laptop (usually a daunting task on a laptop) & clean out all the crud impeding the airflow.  The fan can get clogged and also the CPU heatsink.

Ok, my HDD crashed.  I took it to beestbuy (warranty) and had it fixed.  Clean as a whistle.

Got a CoolerMaster cooling pad.

SOLVED.

Yes your problem was solved. But I just wanna say when you posted your temperature I would of recommended a laptop cooling pad. That what you needed. And thats what they were called

if a laptop needs a cooling pad to work properly, what it really needs is a thorough dusting of the insides.
