m1530 extremely high cpu temps 95+

hi guys.

My cpu core hits the mid 90's when gaming. i undervolted it to 1100v @ 11x and the temps only hit the high 80's/low 90's during gaming but hit the mid nineties in orthos and was still going up.

This is getting me down a bit cus the cpu ramps down during gaming and screws up the fps, and also im outside of the uk so cant get my laptop to dell (there are no dell suppliers where i am)

does anyone have any idea what might be wrong. am i reading the temps correctly? speedfan shows much lower temps (in the 70s) however cpuz, rightmark and hwmonitor all show temps consistent with eachother.

Its a t7500.

there's nothing blocking the outake at the back; i lifted the laptop up during orthos to let air out of the bottom but it didnt make any difference.

I've built a few desktops but i havent really tinkered with this laptop apart from adding more ram.

any help much appreciated as im in a bit of a bind chaps.

 

I think the T7500 I used before went down to 1.07V ... and max temps never went over 65C after that.
Keep undervolting, and consider applying AS5 on it...

 

kebab, for that CPU i cant seem to understand it getting so hot !

mine runs at 2.6 GHz and the max temp it gets is 78 C
-one reason could be a defect on your heatsink or fan not working correctly.

-another could be that they did not apply thermal grease between your CPU and the heatsink...

you can open it up and remove the fan/heatsink and see for yourself, just have a bit of Artic Silver 5 near so you can clean up the cpu and GPU using alcohol and re-apply, doing so will make your temps go lower (i did this and it helped a lot), if not, consider calling dell.

I hope this helps

 

I just took a quick look under the hood. the screws to the cpu (four screws right?) were all loose and needed tightening. did another go off orthos and same temps.

Im going to take your advice and reapplying as5. hard to get things like the rubbing alcohol here but i will have a look.

 

I just contacted dell. i will give you an update hen i have one, but im not convinced they can help me due to my location.

do dell ever send parts and allow you to fit them yourself? i told then that if they want to send mer a new hsf assembly, then im willing to do it.

 

Most of the time they send a technician that screws up things lol.
Na, just let them do it, it`s what you paid for.

 

Yep, dell gives two options, either they send in a tech to fix it, or they send the part to your house and you replace it yourself, your choice

 

lol use Brandy, Tequila ( my favorite), or some other fancy beverage it will give off a drunk-like scent when you use your laptop haha.

Just kidding

i think you can get alcohol anyware from a supermarket to a pharmacy...

 

Hmmm,

do you think i should be angling to see if they will replace the processor?

what are my chances?

I'm thinking i could ask for the newer model, because they run cooler.

 

I had heat problems too. I found a thread here about the Dell wireless card. Open control panel. Double click device manager. Click on network adapters. Right click on dell wireless mini card and click on properties. Click on power management and uncheck "allow the computer to turn off this device to save power." Click ok. Ever since I did that, my heat problems have gone away.

 

Its not the wireless card (which is the intel) as the heat problems occur only when the cpu ramps up.

 

Well, as far as i see, you could ask dell to send in a new motherboard, i really dont think they will upgrade your CPU since it can be removed from your motherboard (unlike the gpu).

However depending on the temps on your cpu ( use HWMonitor to see the peak temps on your cpu)
you can see if your cpu is overheating ( anything over 80C would be far too much for that cpu) and you can tell Dell that a friend has a 2.6 GHz cpu on his m1530 that runs cooler

in short, you can try and chat with a dell tech, see what you accomplish

Best of luck man!

 

hey,

some news... this guy on another forum said to make sure the exit duct for the air is clear. i bought some compressed air and loads of dust came out the back. now it runs fine. the highest it hit was 83 in orthos. not ideal, but much much lower than before and the cpu doesnt ramp down during gaming now.

 

heheh, good to hear!

 

83 is just fine. My T7500 hits 83 at full load in a non-cool room at stock voltages and does just fine. So long as it doesn't go back up with more dust, you don't have anything to worry about now. 95+, that was too high.

If you want lower temps, you probably can undervolt more, but it's not necessary. The temperature drops from undervolting really start becoming noticeable below 1.10V, and increasing the further below 1.10V you go, though, because of the quadratic relation of voltage to power consumption.

 

With undervolting, it should go lower.
I think 1.06V was the lowest I could go safely..
