Looking To Buy A CPU Cooler.

While DRP3 is about 2-3c warmer than D15 at full speed under full load it is also quieter.

How often is your CPU working at full load on all cores?

I usually render one video per day, sometimes two. So, anything from an hour to two +. It's the temps it reaches that concern me; 80+ can't be doing it any good for the long term (even though these things are built to be as tough as nails). :)

I do the same sort of thing. Have you checked the temp of air going into cooler? How long does it take for temps to peak from the time encoding starts? If cooler intake air temp is more than a few (2-3c) warmer than room, (like 10-15c warmer than room) lowering the difference to 2-3c will lower CPU temps by 7-13c, meaning peak temps will be 67+ to 73+ .. definitely much nicer.

I will take a look when I render my next video this afternoon / evening, & I'll report back.

Last night, I took off the side panel to check the motherboard cut-out required for the heavier duty coolers. Just doing that lowered the rendering temps by 4 - 7C.

That is a pretty good clue the case air is heating up either because the GPU is moving air into the CPU cooler intake or CPU cooler is moving more air through itself the case is supplying it, meaning it has to re-use some of it's already heated air trying to stay cool.

Here's a link to case airflow and my way of getting cool air to components.;)

Good luck with that. I'm going to be fitting my new Noctua U14s this weekend.. I ordered it as it was considered small.. but it's certainly quite imposing when it comes out of the box.

First time with a tower cooler, expecting big things.
 
Thanks, I've never fitted anything other than a stock cooler, so I'm going to take my time with it. Hope all goes well with yours, too. :)
 
Suck it up guys! No time to dally about being whimpie here! :p

Honestly, it's not a big deal. Read the installation manual. Look at a couple videos of installing. Install the mount and do a practice dry install of cooler including fans and plugging them in to be sure everything is as hoped for (it will be). Then put a small dob of TIM (size of grain of rice is about all that's needed) in center of CPU and mount the cooler.

As a general rule, less TIM works better than more. We only want enough to fill the microscopic voids in the surfaces, not a layer .. and CPU chips are in center area of IHS, not corners, so no TIM is needed in corners .. a nice round print just reaching the sides is perfect. Below you can see how "less is better". 'Tiny dot' and 'Small dot' are 2-3c cooler than 'Bigger dot' and 'A lot'. :D

I know it's not 'macho' or 'he-man', but ...

"Read instructions carefully" and "Practice makes perfect" really does apply here.

Lesson:
TIM is not literally Thermal Interface Material. It is Tranfers (all directions) Into (anything within a) Meter".

It has an abiltiy to jump large distance with almost no effort .. around corners, into different room .. even ones with doors closed.

Only thing worse we have to deal with around our computers is their Gremlins.

Really !!

I'm as serious as a heart attack!

I may be a little crazy, but I'm not nuts!
 
^^ I was quite tempted by the Akasa coolers, especially their high end ones. In the end, though, the Noctua NH-D15 won out as I intend to overclock my cpu as far as it will safely go. It took a while for this cooler to come into stock; a few more days and I would have probably gone for the Dark Rock Pro 3.

Good choice mate, it will do grand.:)
 
Done. Not to gush too much about noctua fans but i had to look at the damn thing to make sure it's actually turning... It's wonderfully quiet.
 
really not long. 5-10 mins, though i have now realised that i placed the fan on the wrong side (it's currently pushing air against the radiator, but on the same side as the chassis fan is pulling air out the case, i'm going to flip the fan to the other side of the radiator so airflow is in the same direction.)

edit: just make sure you read the right leaflet for your socket (if your heatsink came with various mounts like mine did) and whatever you do don't use an electric screwdriver to tighten.
