E6410 Owner's Thread

I am using 0.75mmish thick copper on the gpu. Running a quad 820qm.

When running furmark, the gpu hits high 90s very fast. I know the processor is a heat generator, but it's not even really loaded just running furmark at 300x300.

Anything else I could try besides the copper mod? Yes I pasted and reseated multiple times. Perhaps AC5 just doesnt work well with this combination?

 

Artic-Silver 5 works fine for me, but you do need to let it sit unused for about 30 minutes before powering ON the system and heating it up. Likewise, do not let it get too warm the first 24 hours. After that, use it as normal and over time - 1-2 weeks, you will see better thermal transfer properties. In summary, the goop works better the more it is broken-in.

With that said, the 820M is a beefy CPU for that system/heatsink.

If I get some time, I will run some benchmarks on my 620M later today and report the temps.

Thanks man. i just tried resitting it again with smaller amount of paste and I think I just broken one screw. Hell Im just gonna use it as it is. It's not like I game anyways so I won't have to worry about the systematic throttling.

 

Do you think it has been worth the time, money, and effort? I can't help but think that you might be sticking with it because of how much has already been sunk into it.

I suppose it could be worth it if you need to run some programs that are highly parallelized, but then it will start throttling. With the i5-560M, I haven't experienced any overheating or throttling, even when running multiple VMs.

For my purposes, the lower clock speed of the i7-820QM will make a bigger impact than more cores, and additional heat/power certainly won't be welcome either. Even the i7-640M is already borderline for diminishing returns...

 

I have the quad in for future purposes. I don't do anything special than say heavy office and multimedia. So the quad core does help. But I figure the throttling won't be an issue unless the cpu is running 80% for a long time. And at that point in the future, i am sure I need to replace the whole laptop anyways. So yeah I won't even bother much now. Let's just see how long my quad will take me.

 

Interesting. How's the battery life?

 

I use battery meter and with 6 cell I get 2 hrs or so. With the 12 cell slice, 5 hours or so. This is on extended battery life mode, good brightness and light office work (in class).

The kind of idle power consumption according to the meter is 20whr or so. It does spike down to 17-18whr but just briefly. It used to be like 16-17whr with the 580M on light, idle. It does look like 3whr, maybe 5whr difference with the quad on very light tasking.

 

That's not too bad, I get about 5 hours on a 9-cell with the i5. It's been a while since I've used my E6410 on battery though, as I usually use my E6220 for travel (it gets 5+ hours on a 6-cell...).

Assuming the throttling doesn't get too bad, I guess you should be good for at least a couple more years.

 

The following shows:
A. The surface temps of the heatsink when idle and under load as measured by a W700 IR Temp Gun.

B. The logged device temps during benchmarking and other tasks. This is a MS Excel file, but does provide a lot of info. CLICK HERE to get it. The system peaks at 82C, but stays within the 60's and 70's C range most of the time; even when under load. This is fine.

C. Just for the heck of it, the benchmarks of my personal E6410 compared to a few other comparable systems using the same CPU and GPU – including a few other E6410's and a E6510. CLICK HERE to see them. I also posted the pics below.

Hope this helps.

Hello,
I´m desperate because I have these two problems:
1. I´ve replaced motherboard, so I had to renew thermal paste on heatsink, but from that time fan noise had grown. Even bought "thermal pillows" for the other chips, because I realised that heatsink does fit only to CPU and there is space between it and the other chips. I had quite noiseless laptop now it is horrible, fan starts and stops even browsing on the internet.

2. From time to time I can´t power it on, it´s shut down properly and I move it somewhere with power plug reconnecting. So I push the power button, then I see BT and Wifi LED blinks, power button blinks twice or three times slowly and I can hear sound like HDD moves heads... and then nothing. Second try usually works and laptom is working very well, there is also NO problem with stand by mode. Once I couldn´t power it on at all when it runs just from battery I try it like 50-times.

Thank you for any response.
