Workstation CPU Temperatures..

Monkey,

Your post was just fine.... breakthroughs are not made by Twitter posts.

Maybe you want to shift over to the "Performance" bigger heatsink/bigger fan that HP has available for the Z800, and I believe also for the Z600 for the one 130W processor HP offered on that.  Here are a couple of prior forum posts to review:

First

Second

The point is that Z600 HP did have that one 130W Max TDP processor configuration (the X5647), and thus I am presuming they used the Performance heatsink/fan also used in the Z800 for that.  Those two workstations use the same sockets, and dual socket placement is standardized.  Those Performance heatsinks are built to nestle together, and have the larger fan that can cool more with less noise.  They also have a third heat exchange tube crossing the bottom.  I have put HP Performance heatsinks/fans in workstations over processors that do not require them and they have run great (and cooler).  That was for an experiment.  I personally think you're running fine as is.

Fans..... the fans HP uses on their heatsinks are PWM type, and are tuned to the motherboard's fan control firmware.  If you put in, for example, a Noctua PWM fan the HP PWM throttle still gets applied automatically and your Noctua fan will run too slow while all your other HP PWM fans will run just right.  It is a balancing thing..... so I'd buy the Performance heatsink/fan I refer to in the second link.  You can buy them new off eBay here for about $50.00 USD.

Here is a pic of the "regular" heatsink, and my post in the second link above includes pics of the "Performance" heatsink plus a listing of the differences, and part numbers:

Thanks Scott!,

'Your post was just fine.... breakthroughs are not made by Twitter posts.'

Haha, This is true

So you're saying the 535588-001 (z800 performance heatsink) will work fine? or is there a z600 performance heatsink that im not seeing in the post's, because the other part no. 463991-001 doesn't show up with anything in partsurfer 😕

I looked into buying the 535588-001from somewhere in the UK, but It looks like its only in the US. With postage a single heatsink would cost me around £60 each, not including the TAX I would incur.  Which is a shame as the actual cost would only be £30 each, which i could easily part with for better cooling.

I did have alook at buying a consumer heatsink and tried to find one which will fit, I got linked to the True spirit 90 but i feel this maybe a touch too big and was unsure if this would actually help cooling.

I also considered permanently removing the Ram cover so I could have the extra room to get a larger heatsink/Fan. Only issue is when it boots the bios knows the Ram cover is missing and kicks out an error everytime you startup.

I know you can skip the warning by pressing by F1 (which is not the end of the world). Would you know of a way to stop the BIOs from looking for the RAM cover so it boots normally? I didnt see any temp changes with the Ram cover off, if anything, having the extra space for heatsinks improved the airflow and temps in the case and allows larger heatsinks to be installed.  Any thoughts?

Thanks for your help Scott.

The partsurfer only lists parts using the HP Spares P/N, not the HP Assembly P/N.  Each part has those two numbers.....  You cannot find every part in the "HP Z800 Workstation - Spare Parts" HP page...... only the regular heatsink shows up there and in the same page for the Z600.

The numbers that start with 5 work for both the regular and the Performance heatsinks in HP's Partsurfer system, and not the numbers above that start with 4.

If, however, you have both types of P/N for a specific item available to you then use both in eBay.  Currently here there are only 3 listings for  535588-001 but a bunch for 463991-001, and some of those are from Hong Kong with free shipping to not just the US.  If you're going to buy 2 at once I'd contact the Alan guys who have about 450 and ask them your more detailed questions about using them on the Z600, and if they can get you a lower shipping price to England.  I have bought new HP parts from China/Hong Kong with zero problems in the past.... that is where they are made, generally by Foxconn.

I personally would not hesitate for a moment to buy those Performance heatsinks and use them in a Z600.  I'm signing off on this thread now, but we all would appreciate you posting back once again if you end up doing that.  Please give us an update on how those cool for you.

Best,  Scott

Hi Scott,

Sorry to be a pain, just to clarify then.. the 463991-001 is an identical heatsink to the 535588-001 its just ones HP spares p/n and the others a Assembly p/n.. but the actual heatsink item are the same?

I think i found a UK seller for the 463991-001,  it even states that  its tested for the z400/z600.  Can you confirm this is what I'm after? the mention of the z800 has confused me abit. From what I understand the part is for a z800 but is compatible with the z600?

Just a YES/NO on whether the link is good or not will suffice. And I will report back on temps once I get round to buying them (May have to wait till next pay day).

Many thanks,

No , they dont runt hotter , they had bad ingineers  🙂  . remove the panel and live it for 10 min and then check again .It was bad designed , or maybe just cheap .  If you have picture I can take a look , I am not a ingineer but I think I could do a better job then theirs 🙂
