heatsink,heatpipes are cold to touch but temperature isn't that bad underload!

[ali.zanjankhah1337]

hello mates,I got my AMD Ryzen 5 1600x OC'ed @ 3.9 ghz on 1.35 V! temps in cpu intense games like AC origins @ ultra doesnt go over 52 c in environment with about 17-25 C,under heavy 100% loads(With furmark CPU burner) it stops at 62 c with custom curved fan speed.the thing is even at 62 or more all pipes are cold or slightly warm to touch and the more further it gets from the CPU it gets the colder(outter parts are cold af),its a big ass radiator and im pretty sure the cooling must be better,btw the guy that was assembling my PC used all of the thermal paste(it was a small syringe, but anyway I guess it was too much).Its not like the heatsink wont get warm at all if i close the side case door I can feel the warm air outta my up-side outtake fan.its not im going above 4.0 ghz anyway but it somehow bugs me that something is wrong with my cooler and still the fan curve is really high.actually can it be from the fan curve? I mean it doesnt let the sink get hot and then gets the fan speed higher or something just sayin xD

Cooler body being much cooler than processor usually means bad heat transfer between CPU and cooler base but your temps look at par for that processor and those frequencies. It's possible that too much paste or some lousy paste is applied.

thank you for replying,somehow I updated info as a new post in the forum my bad,I underclocked cpu to 3.8 ghz and @ 1.337 V and ran prime95 for about 10-15 mins and I hit 72-73 c and when I put my hand over the upper side outtake fan(directly above the cpu heatsink like 5 cm away or less) its still as warm as it is on 60 or 50 C.just correct me if i'm wrong but heatsink must be close to the core temp right? cause i think its not going over 40 45 c on heatsink no matter what temp it is.and outta 8 heatpipes I can reach 4 of them to touch and none of them are even close to being hot.and whats the best way to put the paste on cpu?I can put the heatskin picture if you want.

No, actually not as worm as processor, not even close. CPU core is deep in the package and by the time cooler body heats up, much of heat is already dissipated. Heat pipes also transfer heat by evaporating liquid inside them and carry it up to fins. They are not going to heat up as much either.
What are you using for temperature measuring ? Are you aware of 20c temperature offset in those processors, programs that are not adjusted for it will show that much higher core temps. Latest versions of Ryzen Master and HW Info areadjusting for that offset. HWInfo shows un-adjusted temp at CPU (Tctl) and adjusted at CPU (Tdie) as well as at CPU on second tab down.

If your temps are OK, stop secretly wishing and willing the heatsink to be warmer...

(Does the 1600X also use a 20C offset on temps, i.e, where 70C indicated is actually 50C, etc.?

 

[CountMike]

Yes but as I said, programs should know that and adjust for it. HW Info shows both.

yeah I use Ryzen Master for the info,I know it wont be as warm as the CPU itself but at least close to it?like 10c lesser or something,and btw I already know its probably a too much paste problem.whats the best way to put paste on cpu with a 8 piped heatsink air cooler?

Which cooler is that ? If pipes have direct contact with CPU small amount of paste should be applied to heat sink bottom and spread so paste only fills up cracks between them and than apply a small amount about size of small pea at center of processor. That second part if pipes don't have direct contact. The processor core is just a small part in the center of CPU and that's most important part to cover with paste. Better a little paste than too much/thick layer. In any case, paste should not overflow processor edges, that's sure sign it's too much.

Its an unknown brand its local but its approved ,so copper must have a direct touch with the chip and other metal sides must have paste on them,and a small dot or line in middle of the chip?

Ah, I see it, yes direct pipe contact, use a small mount on paste on the cooler side and wipe it with something like a credit card until (and if) you see only lines between flattened pipes filled up. Than place a small amount of paste at center of CPU.
Btw. that cooler has 4 not 8 pipes. It's very similar to Cooler master 212 Evo.

Just wanted to update,after cleaning and re-applying the Z5 deep cool thermal paste it doesnt go over 58 c under 100% stress @ 3.9 ghz 1.35 V

Great. Nice temps.
