This is my first post, so I apologize if I'm not following any particular protocol or have posted this in the wrong category; please let me know if I need to change or re-post elsewhere. (thank you)
I have a Dell Precision T7400 that came equipped with a single E5405 processor (2 ghz Xeon); on this processor was just a heat sink without a fan attached to it. I am more of a dev than a systems person, but my understanding is that this means that I had a passive heatsink, as an active heat sink has a fan attached to it. (I'm sure that my understanding and definition is an oversimplification of the real difference between active and passive cooling).
I purchased two E5472 Xeon processors, removed the existing processor and heat sink, and installed the new processors into the system (the system was capable of dual processors) and attached two Intel heat sinks with fans that were listed as supporting the E5472 processor (Intel D98510-001 SKT771 Cooler For Quad-Core XEON). Again, based on my limited understanding of processor cooling, this means that this cooling solution for the processors is considered an active solution.
Unfortunately, the system now sounds more like a jet plane than ever. Part of the problem is that there were no more PWM connectors so that the motherboard could regulate the speed of the fan, but I think that even if that wasn't a problem it was going to be pretty loud anyway.
I'm going to try to replace the case fans with quieter models, and if anyone has an general brand or product recommendations I'd love any related feedback you may have. However, my primary question is this:
Can I use passive heat sinks only with two new processors and skip having on the processors altogether? If so, do you have any recommendations or can you point me in a direction to find the right model? Also, is there any harm doing this - does it cut the life of the processors, run the risk of overheating, etc., etc.
Again, per my understanding, I think I'm asking if I can just use a passive heat sink solution for these two chips assuming I have all the proper case fans. Ultimately, I'm trying to cut the noise down; I'm using the system as a Hyper-V server with various servers running on it, so it needs to be on 24/7, and it's right in my home office that I share with my wife and would like make things quieter so we can hear the children running around screaming, yelling, fighting, and otherwise being themselves, because that's a much more pleasant noise than the fans... :D
Any help or recommendations is very much appreciated. Thank you. - Jay
Thank you for your response. I do have the heat sink riser shroud already installed in the system. It covers the memory, memory fan, and the two processors. I'll look tonight to see if the the way it's set up focuses one of the side fans right over the processor. If that is the case, then I think I'd be okay to just use the original heat sink and another matching one.
I'll update this post with further details as I complete these project. Thank you again.
