CCR2004-16G-2S+PC version's technical inquiry - Temperature

[aliaskorea]

Hi,

First, Please understand my english skill.

I have a CCR2004-16G-2S+PC version’s technical inquiry.
Incluse users who are using CCR2004-16G-2S+PC, please reply.

Please will uploading a captured image. - /system health print

I have a CCR1009-7G-1C-1S+PC and 6 May purchased CCR2004-16G-2S+PC

CCR1009 is about 57’C in full load but not more than heat CCR2004.
CCR2004 full load 82’C, Idle 67’C

Will there be any problems in use?

I think CCR2004’s CPU temperature is some high.
CCR2004 is high CPU temperature, but the heatsink is not high warm.

May it seems an assembly problem, such as a heatsink installation problem or a thermal grease problem?
(ex/ Heat sink and CPU is not stick close)

I’m a little worried because I asked a technical inquiry about the heat problem of the CCR1009 of a similar form factor in the 2018 year.

The CCR1009, I use now has no issues and was new purchased at last year. (Exchange from CCR1036)

Fortunately, CCR2004 is good working yet just only have high temperature.

If it have a system issue, it must be replaced within about 2 weeks from the seller.
But when RMA unfortunately, I will may pay return cost, so need an exact answer please.


Thanks.

i think 80+ °C its a worrisome temperature

if back heatsink fins are not hot definitibly there is a problem with thermal interface between chip and heatsink

in /system routerboard have you updated bios/firmware to same version as routeros ?

[aliaskorea]

I am solved. The thermal grease was reapplied after MikroTik support.
The temperature is down max 10~20’C

I leave a feedback about this.

Thank you so much.

I am solved. firmware is updated.

Thanks.

thank you for sharing so detailed info

can you please confirm CPU clock configured on /system routerboard ?

Smart question!

It's same.

If nothing appear, or is the default cpu value, or is auto, or the device do not support multiple cpu frequencies.

[rextended]

I am solved. firmware is updated.

Is NOT updated, still 7.1.4

I would be very interested to know whether one could actually clock the PC version of the CCR2004 to 1.7Ghz like the Actively cooled version

We have had the same exact router model - and the CPU was overheating 103C at IDLE !!!

After reapplying thermal paste now the CPU is at 77C - a huge improvement.

We will replace paste with thermal pads for added efficiency.

We will replace paste with thermal pads for added efficiency.

It’s actually better to use a high quality thermal paste than pads. (Be it silver or ceramic based, would not recommend any of the liquid metal products for use in a router as there can possibly be issues with reactions with the metals)

Pads are normally used when there is a bit of a gap between the heat sink and the component to be cooled (often used on ram chips to help cool them as they don’t normally generate excessive heat). Pads also have a lower heat transfer ability.

The alternative to pads if you want there are thermal sheet products that are reusable, but I wouldn’t recommend them mostly for their cost, and a high quality paste is usually more effective.

I just received s/n HD4086ZNPMY/236 and it shuts dwon after a short period of use. So soon I have no tbeen able to log in.

You are probably right - currently we are using thermal pads and temps are 44board and 57Ccpu on idle - again a bigger improvement than 77C and 103C on idle

When I first exracted the heatsink, the thermal pad was not attached and the thermal paste was hardened.
I think, The thermal paste application seems to be correct and I used MX-4.
