Rx 6600XT core and hot spot temperatures difference

[slaven8981]

Hello,i built my new pc less than year ago and i always had problem with unexpected shut downs while gaming,no errors reported anywhere.

I noticed that my GPU core temperature is max 75C while gaming,which should be fine.But my hotspot temperature is almost always 109C which is max.

Problem is gone with pc case side panel opened,but thats not reccomended long term

I can see that in radeon software or HW Info.

I heard that this may mean that thermal paste pumped out because of this big difference of 34-35C between sensors.

My GPU is under warranty i bought it 9 months ago so should i replace it?

yeah a 109 celsius hotspot is not normal. i'd get a replacement under warranty if it were me.

but it also sounds like you might just have a really bad case, your front fans and exhaust fans working? consider a new better airflow case maybe? leaving side panel off is not a big deal btw, what does hotspot become with side panel off?

Be useful to post which card you are using, but some things going on for sure and this is one of the reasons i buy XFX (US) cards as they always have allowed me to remove the cooler to check. As if a pad is bad or some thing and i can change my self it saves me about $40-$50 due to shipping.

First step would be to contact the manufacture see what they say, check other people with the same card and what temps they are getting to get a idea of whats normal as it might be just a crappy cooler or your case air flow is not up to it.

But to be honest there might be bad contact but all so could be a GPU flaw.

And on top of that mines 66c core and 88c hot spot, you could try in the AMD's application to lower the voltage a little like by 20mV, but some games may crash.

Then the case cooling is pretty bad, fix that instead of bothering with the warranty.

At start i had no additional fans,then i installed one that pushes air out from inside,adding it helped me play some games for little longer before shut down,but i asked people from my country on another forum,they told me its definitely not normal that these temperatures are 35C different, and they told me adding additional fans probably wont fix this,i wanted to check here and on other forums of course.
Hot spot was same 109C with case opened and no shutdowns,my case should be pretty fine,its some kind of gaming case not expensive but has many places for air in/out.
I didnt mention because i wanted my topic to be short,when i tried to play with pc case opened,it was working 1 day like that,but my motherboard died that night,it was AS Rock B550M HDV,i dont know could GPU overheat some part of motherboard so it shutdowns or is it GPU itself.

1 thing that caught my eye is that GPU hot spot temperature instantly rises to 109C under load,so i doubt it has something to do with airflow.

Leave the case open until you improve your case air flow

This is my case,you can see on pictures i can put 7 more fans,i have only this left for air out. Where do you reccomend me to add additional fans.
My CPU temperature is just fine,doesnt exceed 70C.

Those fan holes aren't for show. Fill 'em.

How ever that front panel is restrictive as hell.

 

[Space Lynx]

just put two fans up front intake2x140mm, 1 fan at back exhaust. just very basic setup like that is needed, airflow is needed.

if you still have 109 celsius after that, then RMA the card.

I agree. I don't understand why they make nonsensical cases like this, but I guess people are buying them...

Yeah but it would be very noisy,

Can you show me one one example of good case i dont know about it

It wouldn't if you bought the right fans, there are plenty of near silent high airflow fans available, what you have to do is balance that with budget, 2 decent quality 140mm fans blowing air in from the front with a decent quality 120mm fan taking warm air out of the back of the case will help and maybe get your hotspot temps down to a more reasonable level, you can even set them via your bios to speeds that are not too noise intrusive.

To the OP Arctic is your friend. Inexpensive and great performance.

 

[damric]

Also relevant is your room temperature. If it's 15C you can run your fans very slow and quiet, but if it's 30C then you better have them blasting.

As far as showing you a good example of a case, that would depend in what the definition and purpose of a case is to you. To me, a case is just brackets to mount things, and the ideal case to me looks like this:

 

[AusWolf]

Yeah but it would be very noisy,

That's why you have temperature control in the BIOS and/or in any fan control software you use.
Like others said: fan mounts aren't for show. Don't expect usable temperatures if you don't make sure you have adequate cooling.

Any case that has a mesh front instead of a solid panel.

OP's PC case is more than fine if they didn't screw it up entirely.

RX 6600 XT is a considerably conservative GPU so it MUST be bad die to heatsink contact. This is the only reason why OP gets hotspot this high despite very reasonable average temp.

Contact your seller, make them repaste your GPU or do it yourself. Use something decent, MX-4 for example, or PTM7950 if you don't have a clue how to apply thermal paste in proper amounts.

Or... you lower your clock by 100 MHz and lower your GPU voltage by 50 mV and get by.

OP said the problem goes away when the side panel is off.

 

[Fishworldwar]

This might be a long shot, but could it be an airflow issue?

Also, what brand is the card? Mine is MSI and I haven't encountered any problems with it yet.

Its Power Color Red Devil,its good card,but manufacturers sometimes make mistakes.
I googled more and i found that im not alone with this problem,it happens with Nvidia also,1st step is repasting card.
I would say that shutdowns could be caused by bad air flow,but about temperatures I wouldnt say so,i think i didnt mention that my hot spot temperature rises to 109C instantly after entering video game,thats when my case is cold and i start some game,so thats definitely something bad with card,but i should add more fans.

a bit of necro but thats an issue with thermal interface/bad gpu contact. With a decent, bare die optimized tim like ptm 7950 you shouldnt see more than 12c difference, in my sapphire pulse i applied conductonaut and the delta is only 8-9C even in furmark, at idle its actually 0.

you could use traditional pastes as well (arctic mx 2/4/5/6, noctua nt-h1, deepcool z9, etc), BUT you will get pumpout in only a few months and would have to repaste again.

 

[GerKNG]

RDNA2 has a massive delta (even under water it's often 15-20°C)
but your Cards paste is probably pumped out to a point where barely anything is left.

get yourself some Arctic MX6 (one of the few pastes that don't pump out on GPUs within a couple months like most other pastes on the market)

anything silicone based will get pumped out sooner or later, same goes for mx6. its a good paste to put onto cpu lid, and is user-friendly because its really thin and easy to spread. But its not good for long term use on exposed die (laptops, gpus, you name it)

 

[GerKNG]

i use MX6 on a 3080 Ti, 3090, 5700XT, 6800XT, 6950XT and a 4090 and all of them have identical temps to day one. meanwhile my Kryonaut, NTH2, SYY 157, MX4 and my 3-4 years old tube of GC extreme had to be replaced within 2-8 weeks.
