no i dont hear the fans speeding up,

Not a good sign.
On a laptop when it's that hot, you should be able to hear the fans- especially one with that type of CPU. Even if you can't hear it- it should be blowing a small extremely hot (almost painfull i would suggest) gale out the vents.

even tried to redistribute the hardened thermal paste on the GPU so it was centered again (it had hardened and moved to the corners)

*shudders & twitches at the thought*
Unless in extreme circumstances, if you pull a heatsink off you really need to clean off what is there & put new compound on. Re-using a compund (especially one more than a few months old) usually results in even poorer thermal conduction than you had before you pulled the heatsink off.

yes the fans are blowing out very very hot air but i just dont hear them being louder than usual. i did not know that reusing the thermal paste was bad idea i just figured it was better than nothing. the GPU runs 24 hours a day also as it is doing CUDA tasks for SETI, and i've been monitoring its temp for weeks- it is a steady 57-62.

i've learned a bit tonight, time to retire :) cheers.

there is obviously extremely limited space inside of the laptop so if you or anybody knows of any good additional cooling solutions for a laptop like this one i'd love to hear about it

There's not much that can be done- it's just a case of making sure none of the vents, ducts or heatsinks are clogged with dust, and seeing that the fan(s) are running as fast as they are able.
Running at that temperature you should feel a very strong, very, very hot breeze coming out of the exhaust vents.

About the best thing you can do for laptop cooling is to only ever place it on a solid sooth surface as most laptops draw their cooling air in through the bottom. Place it on something soft or fuzzy & it can't draw the air in.

Something such as Speedfan should let you monitor the speed the fan is running at. Someone else with a laptop might be able to let us know what speed their fan runs at when under full load, but i would expect at least 3,000 RPM.

Far better than that is to keep the laptop on a powered cooling stand when running BOINC. I use a Zalman zm-nc1500, but many other versions are available. You want one which keeps a positive air pressure under those bottom air intake vents that Grant mentions.

I found, in the case of my old Pentium M notebook, raising the notebook a small amount off of solid surface was fairly helpful in cooling. I used Lego blocks to make stands to place under the feet. Raising the notebook 10-15mm. As the exhaust blows out of the back at a slight downward angle I place it near the edge of the table with a few more blocks on the stand near the foot. In an effort to help prevent any hot air getting recirculated.

This seemed more cost effective than buying one of those perforated stands.

I don't remember the make or model, but I found a stand where you can move the fan itself around to where it will be most effective. You feel the bottom of the computer to see where it's the hottest, then mount the fan in the corresponding position on the bottom of the stand. For the first time in months, I was able to play youtube videos full screen without it shutting down.

I am 99.9999999999999% sure I bought it at tigerdirect.com's local retail store.

Sitting on my butt while others boldly go,
Waiting for a message from a small furry creature from Alpha Centauri.

thanks for all the input guys, I am ordering some MX-4 thermal paste as i've read it is a little better than arctic silver (i've always used arctic silver myself but even an improvement of 5 degrees would be worth trying mx-4)

i also was about to pull the trigger on http://www.amazon.com/Cooler-Master-Notepal-Notebook-R9-NBC-4WAK-GP/dp/B002MU1ZRS/ref=pd_cp_e_2
But now that Richard has pointed out the Zalman model, i'm not sure. The zalman models look like much higher quality (also much higher price tag).

They have a Zalman NC-3000U, NC-3000S, NC-2000, NC-1000 etc.. so I'm gonna read up on the comparisons and buy one of these. Hopefully the thermal paste and notebook cooler will sufficiently drop heat so that this system can run higher than 800mhz, otherwise I may have to find a way to keep it plugged in while in the fridge/freezer ;-)

---

I ended up ordering the Cooler Master SF 19, looks like a beast of a cooler and had the best reviews in the $50 price range.

http://www.amazon.com/gp/product/B004G603E2/ref=oh_details_o00_s00_i00

A few updates:

I received the CoolerMaster SF-19 Storm; it is amazing. A bit bulky but I don't mind. It is definitely helping to cool down this laptop. I would recommend that product to anybody looking for a laptop cooler.

I also removed the old thermal paste, and applied some MX-4 thermal paste.

I can now finally run back at 2.8Ghz, but I have to use throttlestop to do so. The CPU's in use 100% and the coolermaster running, its running around 70 degrees according to Core Temp 1.0, and around 60 degrees on Throttlestop's temp monitors. There is always about a 10 degree discrepancy between the two programs so I don't know which is accurate, or if either of them is accurate for that matter. I usually go by the higher temperature just to be safe. I don't yet know if the CPU's will automatically go back to running at 2.8 automaticaly, or if I will have to always use throttlestop to push it up from 800mhz which is where it boots up and runs even with 100% CPU usage from BOINC.

A question: I have found that I can run at 2.8ghz (14 multiplier, where its supposed to be to begin with) while lowering the VID to 1.1 or less (it seems to be at 1.2 by default, and range is 1.0-1.275). Is it okay/does it cause any issues to run it at the lowest VID where the laptop is stable, while keeping the multiplier at its maximum stock number? This seems to be the best way to keep the heat down..

---

As long as it's stable at the lower voltage, stick with it.
If things go odd again, then set it back to the default before trying other options.

Ditto, only instead of Legos I've got 1/2inch semi-spherical rubber stands (they look like those Blue Lounge CableDrops)that came with their own adhesive (sticker). Got them from one of those huge hardware/home stores for next-to-nothing. I too usually pull my netbook to the edge of the desk when I'm not using it:)

That is OK, the program just don't know the proper TJMax.

Get Real Temp
http://www.techpowerup.com/realtemp/

It shows "Distance to TJMax" which is the real (and only) raw value reported by Intel CPUs
(Intel CPUs never report "I have temperature of XX°C", Intel CPUs always report "I am ZZ°C down from the Max allowed")

"RealTemp is a temperature monitoring program designed for all Intel single Core, Dual Core and Quad Core processors.
Each core on these processors has a digital thermal sensor (DTS) that reports temperature data relative to TjMax which is the safe maximum operating core temperature for the CPU.

If the value of TJMax is known:
Absolute Core Temperature = TJMax - DTS
"
http://www.techpowerup.com/realtemp/docs.php


So I say:
You can safely rely on "Distance to TJMax" to know how far is the CPU from the Max.


All programs read from DTS the value of "Distance to TJMax" (on Intel CPUs, AMD is different).
The little problem is if they don't know the proper TJMax they just calculate wrong:
T = TJMax - DTS

I'll bet CoreTemp thinks the TJMax is 100°C (so 70°C = 100°C - 30°C)
and Throttlestop thinks the TJMax is 90°C (so 60°C = 90°C - 30°C)

See, both know that the CPU is full 30°C from the Max (whatever it is)
(you start to worry if the Distance is 5-10°C)

P.S.
If you manually change TJMax to 150°C (which only changes some value/variable in the program and nothing more, safe to try)
the temperature will be reported as:
120°C = 150°C - 30°C

Again - nothing to worry about, the value 30°C is the important number.

Not to be confused with this tjmax: http://www.tjmaxx.com/

:)) I never heard of this (clothes company??)

The author of Core Temp calls this Tjunction Max or Tj. Max
http://www.alcpu.com/CoreTemp/howitworks.html

It is supposedly the Maximum Temperature at which the Junctions inside the CPU still can operate without melting/burning.

Both cores are pretty steady at around 46-48 Celsius, at 24/7 100% use from BOINC.

So it's definately not running near it's full speed.
My C2D E8400 (2.4GHz) with stock everything generally runs in the high 50°s with the ambient temperature in the low 30°s, mid 30°s it runs around the low 60°s.

So basically my multiplier should be at 14, right?

Yep.
For that bus speed & the CPUs rated speed, the multiplier needs to be *14

C2D8400 is a 2.4 GHz clock speed? the processor clock rate constant is 3000 MHz (9 x 333 mhz). Why do you keep it below the manufacturer clock frequency?

I have a random question, but rather than start a new thread I'll just post it here:

I noticed that some of the top 20 computers in the statistics page have more processors than sounds right.

For example: GenuineIntel
Intel(R) Core(TM) i7-3930K CPU @ 3.20GHz [Family 6 Model 45 Stepping 6]
(12 processors)

and

GenuineIntel
Intel(R) Core(TM) i7 CPU X 980 @ 3.33GHz [Family 6 Model 44 Stepping 2]
(12 processors)

Arent those CPU's 6 core and 4 core? Each of the computer also has 6 GeForce GTX 590's, but I didn't think those were listed as processors. Like my C2D systems that have 1 GPU don't say "3 processors", they only say "2 processors" as is normal for C2D.

Anybody know why those systems would say 12 processors?

Can't think of an answer shorter and more to point.

But back to the Forum Thread, Core Clock Speed
and how it's approched and achieved, since the Memory Controller resides
in the CPU! That is Core I7-xxxx |I5-xxxx and I3-xxxx.

My I7(-2600) CPU, mobo INTEL DP67BG, derives all speeds from a 100MHz clock,
(oscillator), the I7 runs a 34x to 38x multiplier, if enough load is present.
(Turbo-Mode), a lesser load drops the multiplier to ~12x to ~16x.
It, also can up the speed, when using 1 or 2 cores, 3800/3700MHz.

With the 'older' C2D | C2Q(X), using a North- and South Bridge, were North Bridge connects CPU and memory, also PCIe busses, Southbridge
communicates with the storage devices.
From WkiPedia
Noth and Southbridge..

My 2 older ASUS P5E mobo, uses a different approch to set the CPU clock-speed.
Apart from changing multiplier setting, which works bad on this mobo, it uses
memory speed, not FSB, f.i. 375MHz. (x2 is memory speed, 750MHz. FSB=1500MHz).

CPU uses, stock, a 9x multiplier, so CPU speed is 9 x 375=3375MHz. (DRAM:FSB =
1 : 1). But this can be changed, too, as my LT does, it uses DRAM:FSB=2:1.

Those mobo are easily OC'ed, if you keep the multiplier-setting at 9.
My QX9650 runs at 3550MHz. DRAM is at 395MHz. FSB=1578MHz. (At 1600FSB it gets
unstable, but if DRAM speed can exceed 400MHz. 533MHz. f.i., FSB would be 2132
MHz. and CPU at 4797MHz. Unfortunatly this board can't handle those speeds.
A higher multiplier setting, 10, 11 or 12, would give more acceptable
FSB and CPU speed.
