Z440 CPU Temperature Issues

[nayfhen]

Hey everyone, hope you all had a good christmas, I recently received a Z440 Workstation and upgraded the  E5-1603 v3 to a 1650 v3, and installed a 1660 super into the case, however my cpu is

currently running at 80+ degrees celsius when running games and around 65-70 degrees when idle, however my GPU runs fine at 60 degrees. I gave it a clean today and after the results seemed to be a little worse and the temperature got even higher. I was wondering what could be causing this, I have the 700W power supply with 64GB RAM. Thanks in advance for any help given 🙂

I'll help get things started.  Above a certain amount of RAM HP specified that the Z440 memory cooling solution should be installed.  Is it?  It is best seen quickly by an eBay search for 748779-001.  If not buy one and install.

Second, do you have a front cooling fan installed?  I can get you the part number for the black plastic fan holder and fan, plug and play, which increases the front-to-back airflow.  If you don't have this do get it.

Third, do you have the large Z440 heatsink/fan?  See that via an eBay search for 749554-001.  Some Z440 builds came with a smaller heatsink/fan but both of the processors you mention have max TDP 140W.  Strange things can happen after a box leaves the HP factory, however.  This one has double the fin surface area and 4 instead of 3 heat tubes, and obviously if you don't have one of these you must get it.

DGroves has a way to see what temperature is in expected range, vs too hot...  The Xeon processors run hot... they were designed for that.  Brian1965, also, has a favorite best thermal paste and he pushes the limits of performance and cooling.
