Question Cpu overheating after installing new graphics card

Installed a rx 6700xt yesterday and have been experiencing cpu overheating.Temps were around 40 C at idle but under load would push to 90-100 C ,browsing would bring it up to 60-70 C.

Cooler is a thermaltake th120 argb that I have been using for the past year without issue.

I have tried a couple of fixes ; mounting my radiator to the front of my case, shaking the radiator, remounting and aping new thermal paste on the cpu, switching fan headers; all to no avail.
I fear my meddling might have done more harm than good as temps now increase up to 80-100C at idle.

Extra info: I can feel vibrations in the tubes although much more pronounced in one tube than the other. The warmer tube is warmer closer to the cpu block opposed to leading to radiator.
Specs : i7 10700k, 650w psu, Asus TUF B560m plus

Any help would be much appreciated, thanks
 
What gpu did you have before the 6700k? What were your temps before the temps you are experiencing now? My first instinct is that the 6700xt is a high heat producer and it is overpowering your one fan cooler on your 125 watt cpu. If you turn the cooler and case fans to high is there any difference in temps?

Had a gtx 1060 6gb, was not experiencing any throttling so did not check temps. Ran the fans at high and still went up to 90-100 idle, took a little bit longer to do so however.
 
Ok so I think your cooler needs replacing then. Not from the gpu heat, but from some kind of failure internally. You indicated you felt vibrations in the tubes. My suspicion would be the impeller in the pump probably froze or disintegrated. Your cooler was doing a tough job cooling that 125 watt cpu. Since you already tried reapplying paste, moving the radiator etc. I would guess a newer/larger cooler is in order. Imho.

A newer, better cooler would probably be for the best, thank you so much for the help.

What is the make/model of your case?

The small radiator of the tt120 is probably not good enough for your cpu.
But, I see no reason why the cpu heat should have become greater just because you added a hot graphics card.

AIO coolers do not last forever. Air intrudes and pumps deteriorate and fail.
Still failure after a year is premature.

You should probably be using a 240 sized aio that you could mount on top.
If there is room to mount two front intake fans to feed the 240 aio, I think you will do better.

To help with gpu cooling, mount a slot fan under the gpu to draw cooling air past the gpu fan intakes.

Case is a MSI MAG Vampiric 100R. Unfortunately I cannot mount a 240 aio in the front as my gpu is a little bigger than my case clearence so it blocks a 120mm fan slot in the middle of the case. Not sure about mounting it on top as my motherboard does get in the way,the fan installed at the top left of the case is done so just barely with 2 screws.

I'm thinking of getting an air cooler instead, currently looking at a dark rock 4 or dark rock tf.

Noctua maintains a list of suitable coolers for your processor:
https://ncc.noctua.at/cpus/model/Intel-Core-i7-10700K-416
You case has a cooler height limit of 160mm.
I think the strongest would be the NH-D15s.
The NH-D15 is too tall at 165mm.

The drp4 is similar, but may impact your ram sticks:
https://www.bequiet.com/en/cpucooler/1376

The dr tf is a downdraft cooler which is generally not that effective.

Relocate the top fans to the front to increase fresh air intake.
All the intake air will exit somewhere, taking component heat with it.
Top exhaust fans may be counterproductive. They tend to divert the cooling airstream up and out of the case before doing any good.

The noctua dh15s is a fair bit pricier than the dark rock 4 in my part of the world. How would you rate the dark rock 4(non pro) against the dh15s?

Performance may be about as good.
My concern would be with the height of the ram sticks and possible interference.
Check out the technical data which shows height allowances:
https://www.bequiet.com/en/cpucooler/1376

Here is the same data for the NH-D15s:
https://noctua.at/en/nh-d15s/specification

Note that the black version may be much more expensive than the traditional beige.

My understanding is that the dark rock 4 interferes with the first ram slot :

I don't plan on filling out all my ram slots in this pc build and the ram that I do have is 35mm tall(hyper x fury) so I should meet the 40mm clearance.
I really wish I could go for the noctua dh15s but I'm afraid my budget does not allow it.
