Older the CPU, higher the temps?

So I've got a used Xeon X3460 last week, and its temps are really really high..
I was previously using a core i3 540 3.1Ghz OC to 4.1Ghz with stock fan and the temps stayed below 72C

Right now, I'm using this Xeon X3460 2.8Ghz Downclocked to 2.3Ghz (to maintain safe temps) and temps still go up to 75C (HT Enabled) and using the same stock cooler

I've asked the seller of this processor about what fan he used and he said that he used a stock cooler with stock clocks and the temps stayed below 65C..

So does this mean that older the processor, higher the temps? Or is it my motherboard's fault?

I've also run some CPU temps apps and the older version of CPUID's HWMonitor and its new version, and the older version shows temps show temps around 13C lower than the new version and other apps show the temps identical to new version of HWMonitor..

So which app can I believe in? Or is it my mobo's fault for wrong temps?
also my mobo is an Intel DH55PJ

PS: I've thrice checked my Thermal paste configs, nothing's wrong with that and I use the cooler master master gel pro..

Looking at the info on that processor, it makes sense that it should run hotter on the same cooler. For one thing, it's a 4-core, 8-thread processor, while your i3 only had half as many cores and threads. Additionally, it is from a slightly older generation, and built on a 45nm process, while your i3 was built on a 32nm process. As the process shrinks, energy efficiency tends to get better. Because of these factors, Intel rates that i3 as having a 73 watt TDP, while they ratethe Xeon as having a 95 watt TDP, which is the energy that the cooler should be able to displace. There are some differences between Intel stock coolers, and if your i3's cooler was only designed to dissipate enough heat to handle that processor, it might...

The stock cooler for an i3 540 is much lighter than the one used for i7's / xeon x's. Get an aftermarket cooler and you are good to go.

There are some differences between Intel stock coolers, and if your i3's cooler was only designed to dissipate enough heat to handle that processor, it might struggle to do the same on a CPU with a 30% higher TDP.

And of course, the rest of your case's cooling could make a difference. If there's not a lot of airflow in your case, the cooler might struggle more.

But at least it should be powerful enough to keep it within 72C at stock clocks? I've asked the seller if he had used a copper based stock cooler and he said it was complete aluminium, so it can be my motherboard's temperature sensor? Or is it that its my fan? I'm thinking to upgrade to a CM Hyper 103 and that'd be enough, right?

Well then fine, whatever the reason is, I'm thinking to but a CM Hyper 103 with 3heat pipes, would that be enough to keep the temps below 72 for this processor at stock clocks?Or should I save up for the cheapest Liquid cooler/DC GamerStorm Maelstrom 120mm?

My intention is just to keep the temps safe, I'm not really going to OC it and to keep the temps safe for stock clocks, is hyper 103 going to be enough?

Just get the hyper 212 which is 5€ more but a lot better.

Really appreciate the replies, thanks a lot :)



The Hyper 212 isn't available where I live, there's hyper 212X which costs twice, though I hope decrease of just one heat pipe isn't going to make a much of a difference between their results..
