E6400 overheating throttling

Sounds like the throttling problem to me. What BIOS version do you have?

 

1. What temperatures are you getting?

2. Check if the cooling system is getting clogged up.

3. Read this thread and this thread which describe a similar problem and the solution.

It gets up to 81c before deciding to clock down to 798Mhz. It then hits 40-ish degrees C and the cap is removed and it shoots back up to 2.66

I shall have a look at the cooling and those threads later today

Thanks

 

I've been having this problem as well for a week or two now on my E6400. I have a T9600 CPU, NVIDIA GPU, 8GB of RAM and I'm running Windows 7 Ultimate x64. I went through a complete reinstall of Windows 7, all kinds of driver changes, assumption of it being malware/virus and thinking it might be Symantec Endpoint Protection before finding out about the overheating threads and the pdf. I was running CPU temps in the high 50's and a GPU temp of 78 degrees Celsius before. I reloaded the A17 BIOS and then hammered up a Nintendo emulator and some games with some full motion video, Outlook 2010 beta and some other IE windows and neither core cracked 50 (the GPU is currently sitting at 65.) I'll keep an eye on it but for now A17 seems to have fixed my problems.

My most recent backup had severe corruption issues as well so I'm kicking myself for not doing more research on this before but I'm not thrilled with Dell about this either.

 

Your problem is probably could have been fixed with a motherboard and heatsink replacement. Most people that with the Nvidia GPU, have had their overheating problem solved this way.

 

Is Temp1 in Speedfan the temp of the chipset? From what I've read, when the chipset gets to 55C is when the fan kicks in to full-RPM. Is that right?

I'm looking to buy an E6400 soon (with nVIDIA), and I don't want to run into the throttling issue.

 

That is why I don't use temperature reporting software that doesn't support the system. I use Everest, as it seams to support this laptop nicely (and my other systems). However, it is a paying one.. but for a first run.. their is a trial version, which is usually sufficient.

The throttling issue is now solved since BIOS A19.
Those who still have a throttling issue, got it solves with a new motherboard and/or heatsink replacement. Something else to consider, is that for MOST (but not all) people who had the throttling issue, it was affecting Intel GPU users, rather than Nvidia's solution, which is kinda of ironic in a certain way, as it's unexpected as Nvidia solution heats up more.

And if it makes you sleep better, as I state several time in the forum section, I overclock my GPU like no tomorrow to play games at higher settings smoothly without any issue (see signature on my OC guide, to see how much I overclock it). The system doesn't struggle with the extra heat (no cooling pad used).

When my system is plug-in for a while my chipset is at 55C already, when I just web-surf and or program (typing text, not compiling). Note that I set my GPU to go full power when plug-in. And, obviously I face with no throttling, and my fan is not even spinning. I know the fan will eventually kick in, as I am plug-in and everything is going full power, especially after I visit a page with lots of ads (especially java or flash based ads), or watch any sort of video.

In a normal world, processor can handle 90 to 110 degree Celsius before they complain and throttle or crash for safety purposes. 100-110 degree is common for CPU's and GPU's. 55-56 degree is very cool for a processor. A few years ago, we used to have processors that ran idle at 70-75. What we have now is luxury, and as time passes, we create smaller and smaller processors which heat less (and consume less power, so that we can have it more powerful). In laptops, this is done extensively as battery technology is moving extremely hyperly slowly. Not because that they are no investment, but because you have to consider, that it's extremely hard, you have to find the right mixture of elements and material, and beside all that you have to "cross your fingers" that it can be rechargeable, and beside all that... cost. If it uses titanium (let's say), or some hard to extra element.. than it's not interesting. Anyway, I am going off topic here...

Back to topic... when my fan kicks in.. of course my temps lowers.

 

GoodBytes

Totally disagree this is absolutely not true! They do not have to do ANYTHING to this thing work ! THEY JUST CUT COST. They can use:
- thicker heatpipes ( 1$ more)
- all copper radiator (3$ more)
- Arctic Silver 5 , bought in BIG quantity (1$ more)
- SSO Bearing in fan (2$ more)
- Mainboard on bottom (heat dissipate toward UP not bottom, in the effect current solution keeps warm air nearest soldering points of chipsets)

So PLEASE do not start with "mighty rocket engineering" , they just F...k around cutting cost thats - SADLY - ALL! Try to think aren't they implementing somthing like "Sony Timer" ? Even if NOT, still all this problems came from excesive savings they made.

 

yes.. and what you just said is billion of several million less. Niiiiice...
Heat desepation has nothing to do is the CPU is up down left or right...
Yes HEAT goes up... but we are cooling it off directly. Open a gaming desktop computer.. see that BIG FAT card (http://ipon.hu/_userfiles/Image/joker/hirek/081216/nvidia_geforce_gtx_295_04.jpg)

Notice how the CPU, heatsink, fan is pointing down EXACTLY like in a laptop. And we ALWAYS did this. In the old old old days, it was actually the contrary, the way you said it. The flip, doesn't "reduce costs", it's the same thing for graphic card/sound card/etc... manufactures. In fact doing the flip means modifying machines, which is VERY expensive to do. So why flip, when it's not needed. Do you think for a moment, "they did not know". You have thousands of engineers working for a company, doing simulations non stop, and they could not figure this out? Is that what you are saying?

The cards were flipped for many reasons:
1- soldering points of chipsets can handel way more heat than the dissipated heat.

2- copper radiator... It won't help. Yes copper conduct heat better... compared to plastic yes... but compared to a metal with copper in it, it doesn't make difference. What helps is metal surface. More surface you have, the better cooling you'll have. That is why the heat pipe is in copper, and the fins are not needed to be in copper.

3- Thicker heatpipe, means much heavier laptop... copper IS HEAVY. And in my opinion, the heatpipe is already bug enough. AND the metal laptop base is used as heatsink as well.. If hey were cheap.. they would used a laptop base made in plastic NOT a MAGNESIUM ALLOY, which costs way more than your solution.

4- Arctic Silver.. is not a pad.. it's a liquid. Pads are easy to install, and you ensure that EVERY laptop has the right amount put. Remember that you have a human that puts the dosage, and needs to put it quickly. They COULD have a machine that does that.. but that means loading all the prepared heatsink properly in a a machine, which then adds the thermal paste, and you need someone that takes it and run to the laptop in the hope that no (well a too large amount) dust particle arrives on it, and install it. What you are asking is MINIMUM 4 employees instead of 1, slowing down the build time assembly so that heatsink can be loaded in a special machine, AND have that special machine custom made, which is more millions of dollars of engineering, PLUS make the machine itself to have it at all the assembly facilities, AND train the employees what to do, AND train the employee in safety, AND supervisors (1 supervisor can't be here 24/7... so you need at least 2 doing a switch), AND have them at every facility. Oh and you are also destroying the optimized build assembly which was done by a bunch of other engineers. In addition to all that, you have to see if Arctic Silver can PRODUCE the needed amount by Dell. So what you are asking for is BILLIONS of dollars, JUST for some thermal paste.

5- SSO Bearing? The fan is quiet enough. What makes MOST of the sound is not the motor.. it's the AIR itself. Lift the laptop form your desk, and notice how the produce sound changes. now remove the bottom panel, and it changes again. The motor of the fan is VERY quiet. To reduce fan noise, they must make bigger air wholes (which is bad, because unwanted stuff goes in), bigger fan, so that air can circulate slower, so less noise, and even all that your still have the problem of the air passing through the heatsink fins. Why do you think a desktop heatsink is HUGE in comparison.. because it can afford all that... a laptop can't!

As much as I actually do enjoy being corrected, as it's all in the process of learning. I don't like being corrected with false information.

Every company wants to cut costs... yes... obviously. This is how you grow, and attract investors, which allows you to grow even more. But, doesn't mean anything they produce MUST be .. If they wanted that... they could have simply used: standard plastic hinge, cheap plastic laptop base, ensure that if the laptop drops it breaks, so that people go and buy overpriced replacement parts, glossy screen, Remove those 2 support beams inside the laptop, which is there to reinforce the laptop to reduce flex from the palm rest and keyboard (did HP had 1 system where if you press on the ENTER key (or it's surround keys) hard enough, it actually presses on the optical drive making a disk stop and scratch the disk?!), cheaper keyboard.. well I can go on.. they could CUT on A LOT of stuff if they wanted. That is my point.

AGAIN, and again and again, I freaking overclock my GPU (see signature), like no tomorrow, and I have NO ISSUES. The laptop handle heat PERFECT.

Also What does all your saying have to do with my battery comment? Where you trying to say that in reality we do have this super battery that can give us DAYS of battery life under heavy load by a gaming desktop, and fit in your pocket, but companies are too cheap to use it? Because if you know this, I would really would love to read an article on that magic battery. And PLEASE< don't talk to me about Apple battery, because their battery is less thick yes, but longer.. and they don't even use 98-99% pure lithium-ion.. hence why the battery swollen and destroys the laptop, which Apple doesn't cover in their super vague warranty fine prints.

 

Actually the best coolers for GTX are changing that: Thermalright HR-03 GTX Rev.A - that could be set for downward bottom of case or upward ... so I do not see this as good point in this argument.

Are you serious? Then WHY fins in M4400 are ALSO made from copper?

Why did they change cooling just after first batch? EXPLAIN this to me? Why they change size of heatpipes i E6500 and M4400?
Again, very funny ... 0,5 mm bottom transists heat - LOL. It is paper thin. It is as cheap as ABS plastic used in Lenovo. No point here.

4 Big US&A company has problem with applying thermal paste (it is NOT liquid) - laugh or cry? Machine for applying thermal paste .... sad, really... Do you even believe what you are saying? That DELL is UNABLE to automate applying thermal paste ...

5 ... yeah, and Noctua and Lenovo use owlish design of fan just for fun (and patented it also for fun ) ?! Liquid bearing that are used in HDD are capable of quiet working with almost 7200 rpms and are designed for loooong period of use (cost, well cheapest HDD is 40$ so I could assume that motor is cheaper than 15$).
