Latitude 7450 Owners' Thread

Here's a thought: Get a small piece of aluminium cooking foil and stick it on the inside of the bottom shiny side up (a glue stick type glue should be adequate) so it reflects heat back towards the fan and heatsink area. Just makesure that there's no exposed metal in the computer which the foil could touch. If I get bored tomorrow I might try this on my E7450.

10+ years ago I had a Fujitsu notebook or two which overcame the hot bottom problem by having a thin layer of felt glued onto the outside. That was a very effective insulator.

thats an interesting thought, however, i believe, that would further increase temperatures on the cpu have some read somewhere that there are a few versions of heatsinks that might affect the cooling: this one seems to perform better than:

However i still got dells warranty so i guess i should not play with that myself not to void it

What i do not understand is why they take away the ability to change the settings when the fan kicks in... 65 or 70C is way too long to wait for active cooling...

 

Using some foil to reflect some heat back to the heat sink will help get the CPU up to the temperature where the fan comes on.

Alternatively, if you apply a thick layer of thermal paste then the CPU will run a bit hotter and reach the fan threshold sooner. However, it's also likely to cause a noisy fan under full load conditions.

Did you try the different settings offered by the Dell Power Manager?

Yeah i did try different settings no major difference

 

Would using two mSATA drives with one of these work?

I cannot find information anywhere if the E7450 supports port multiplication. Im sure it would work in a RAID configuration, but would it work in JBOD as two separate disks?

 

You may get some insight by reading through the questions and reviews on the Amazon page. For example, someone who has used the device with the E7240 reports a short working life - I didn't read further.

I wouldn't try using one of these unless I had two spare mSATA drives lying around. The adapter will not improve the read performance because most recent mSATA SSDs can saturate the SATA interface. If the notebook's SATA can support port multiplication there won't be any increase in throughput. If you are wanting more capacity then the safe route is a larger capacity SSD and put away the old one as an archive of everything at the time of the switchover.

Thanks for the reply. I saw the comment on reliability, though I wasn't really clear on what he was doing... it sounded like a lot of installing/uninstalling. Also, there are other brands who make this sort of adapter. The bigger question (for me anyway) is if the E7450 supports port multiplication. I do have a second mSATA drive available to try it, but I would be out the cost of the adapter if it doesn't work.

Just to fill you in, I like the idea of having two separate drives on my computer. I could do a RAID0, but I am not interested in faster speed (and as you pointed out, I might not get it anyway). I would like to use this as two separate drives using an adapter such as this. Everyone else on this forum is searching for a way to use a second drive in the WWAN port, but if something like this works, it seems like an easier solution. Maybe I just need to pony up and try it

 

The discussion here indicates something similar worked in an Alienware notebook. However, the only way you are likely to find out if it works on the E7450 is to try it. If the port multiplier option doesn't work then would RAID BIG provide a way to access the capacity of both SSDs, so the cost of the adapter wouldn't be wasted.

Hello everyone,

has anyone tried this SSD as a second drive in the WWAN slot of the E7450?

You need to find an M.2 SSD with PCIe interface (and no one else has found one yet). That SSD is SATA. It is very confusing as both interfaces are options for SSDs which conform to the general heading of NGFF / M.2. The M.2 SSD slots in some notebooks can use either interface, but this capability has to be built into the notebook hardware.
