C2D T9300 in a Lenovo G530

Hi, I'm sure this was already asked before but I'm finding mixed values on the net. I installed a T9300 to my Lenovo G530 the other day. Then I was getting idle temps of 47-50C and 83C using prime. I was surprised coz when I had a T8100 installed i was getting 37-40C idle and 71C on prime. Are my T9300 temps normal? Would like to know what your T9300 temps are before i do anything to my laptop. By the way, a already re-applied thermaltake thermal paste twice so i gues its pretty much seated to the heatsink. Any feedback will be appreciated. Thanks!

 

The values seem to be within normal ranges though you have to bear in mind the T9300 runs at a higher clock rate than the T8100 so you do expect it to run a little hotter. That said I have a T9300 in my 14.1" ThinkPad T61 and it idles 40-46c, and under load in Prime it's 68c (though core temps are 58-61c). Though my ambient temps are pretty cool, around 20c around where I am.

The trick is when applying thermal paste is not to overdo it, a thin layer will do the trick. For easier application I tend to use masking tape and seal off the edges only exposing the die, paste carefully applying even coverage then remove the masking tape for a clean result.

 

Thanks for the prompt reply. So is it safe to say my chip is normal? Im a bit concerned i may have gotten a bad chip. I'm using Real temp for my temps by the way. Is it right that TJ max is set to 105C or should i calibrate it to 100C? Also, my GPU thermal pad is somewhat torn, could that also be a factor for my high temps? Thinking of re-applying thermal paste again, hopefully it will lower my temps a bit.

 

The T-Junction is fine, 105c is the correct TJMax temperature for the T9300 as stated in Intel's spec sheet so no need to do adjustments. However it may be wise to put a new set of thermal pads to replace the torn one on the GPU so it can plug any thermal gaps, thankfully they're should be relatively easy and inexpensive to acquire.

 

Should a 1.5mm thermal pad be fine? The old thermal pad is a bit deformed..I dont think i can measure it accurately.

 

1.5mm thermal pad fits just right for my Lenovo G530 GPU heatsink.

 

Just an update. After replacing my GPU thermal pad on the G530, my laptop runs a bit cooler now. I'm now getting 42C on idle and 76C using prime. of course I re-applied thermal grease on the CPU.

 

Have you undervolted using RMClock? I did this on my m1530 and massively dropped temps. There's a guide on the forums called the undervolt guide. Follow it and let us know how it goes

Spreading thermal paste out in thin layer is the WORST thing you can do, it creates a cushion of air that gets trapped between the heat sink and chip, thus hurting temps because air is a very poor heat conductor.

You want it to be completely air tight.

Throttlestop does the same thing, is still being developed and consumers less CPU cycles. So I recommend Throttlestop over RMClock for undervolting Core2Duos.

 

Used ThrottleStop to undervolt my t9300 down to 1.05v. i got less 10C on my chip using prime. Thanks for the tip

 

Hello, I will be applying thermal paste when my cpu arrives. You say speading it into a thin layer is the worst thing you can do, so I need to know how exactly is the best way to apply it. Thank you.

 

First method in that video link, ie: Dot method.

 

Oh ok thanks, I Didn't See that link the first time I read it. I'm reading in other places and it seems alot of people use the cross pattern too, Is that okay ?

 

Since mobile processors dont have heat spreaders..the dot method will do just fine.
