Dell Precision 3650 MT CPU stock Heatsink/Fan Upgrade/Replace

Yes, you can use the OEM premium cooler for your T3650.  New cooler can be source here (last one).

Hi CdO.

Thanks once again for helping me out, confirming that this swap *is* possible. 

I am looking into finding someone selling this in Europe, to reduce cost since I live in Greece and total cost + shipment + taxes add up so much as to make even a liquid cooling system a vfm alternate option. 

I've also noticed that you don't propose to buy the vrm module along with the main heatsink. Is it because you think my system (being a 65w i7-11700 cpu) don't need it, or is it because of extra cost? 

There are two more things to ask for your advice: 

First: Are there any aftermarket low profile heatsink/fan system options (ideally total height should be up around 50mm) to replace the stock Dell combo, that would actually fit in this case and that you would recommend?

Second:  Do you think that a Corsair H60 liquid cooling system would fit in my MT case and that it would serve better my CPU  cooling needs? I've seen a comment about this but was installed on a 3630 Tower case and I really don't know how difficult it would be to fit this unit in my Mini Tower case. Dell is only popular in business environments here in Greece and there's hardly any user experience and experimentation from individuals so actually no one to ask.

This is the thread I was talking about: https://www.dell.com/community/en/conversations/precision-fixed-workstations/dell-precision-3630-liquid-cooling-with-corsair-h60/647f8484f4ccf8a8de3666cd?keyword=3650%20precision%20corsair%20H60 

I will be looking into it and if I come up with something interesting I'll post it here for everyone to know.

Thank you for sharing your knowledge and helping me out with this, too.  
Take good care of yourself!

Sorry, I forgot about your location and providing link to US, which is where our community is base.

You are correct with your assumption, no VRM heatsink was suggested due to both, cost and requirement.  That was a good thread with many valuable information about liquid cool for your system as the chassis is very similar.  However, I can't confirm if the H60 will fit as I did not use one.

Besides confirming that Dell premium CPU cooler would work, upgrading the top fan to a 120 mm will be another resolution to resolve thermal issue as they both working in combination to remove heated air from you system instantly.   

While many of low profile coolers from Noctua, Silver Stone, and others may fit well in your system, they don't improve much if they will just circulating the heated air around inside.

@Chino de Oro​ No need to be sorry. US market is by far the best cost effective market for us, even with European wages. It's the shipping/tax costs that add up considerably and make this option a bit on the pricey segment. There are potential sources in Europe, too, especially through Germany. I may even ask Dell Greece to see if they can provide me one at a reasonable cost (although unlike to be the cheapest).

But you have one more valuable suggestion here (upgrading the top fan to an 120mm), along with the stock Dell heatsink that is. Thank you! This would certainly help and it will be the first to try...

I have to say that these days we're under severe heat attack and air temperature inside the house is about 30 degrees Celcius (about 86 degrees Fahrenheit) when temperature outside (and under shade) reaches about 43 degrees Celcius (109.4 degrees Fahrenheit). I think this too, puts a burden to the i5-10600 stock dell heatsink/fan combo I use with my i7-11700 65W CPU. 

So, I will look into the proposed solutions, evaluating cost/effectiveness and maybe come back here to report the solution I finally used to solve it, for the rest of us to use, if need be. 

Once again, THANK YOU!

Take care,
