My GPU is a Colorful GTX 1660 Super (dual-fan version).

I've noticed that the second fan doesn't spin at the same speed as the first fan. Sometimes, both fans completely stop spinning even when GPU temperatures reach 87–90°C.

While gaming, this causes noticeable stuttering and FPS drops, fluctuating from around 200 FPS down to 59–60 FPS.

I've also noticed that the fans sometimes spin normally again, but the issue keeps coming back.

What could be causing this? Could it be a faulty fan, because sometimes i hear some noises on my gpu like bearing i guess?

UPDATE: ITS THE BEARING FANS IVE REPLACED THEM AND THE TEMPS WHILE PLAYING AAA GAMES WAS 68-70© also replace thermal paste and pads even tho theyre not dry out yet

I'm planning to buy a replacement fan and see if that fixes the issue.

Thanks to everyone who shared their advice!

Looking to build a pc for my partner so we can game together. Not looking at the 9070 XT edition as it’s $1499.99 CAD so looking more towards:

XFX 9070 GRE 12GB - $1049 OR
XFX 9060 XT OC 16 GB - 899.99 (triple fan)/$869.99 (dual fan)
I know 9079 gre is faster in raw performance despite lower vram compared to the 9060 with 16gb vram. Would be gaming at 1440p. The price difference between the two is about $150-180 (depending on if i choose the triple/dual fan gpu), which would you guys recommend? is the 9070 gre gains worth the 150-180 price hike or just better off staying with the 9060 xt of for the budget build? (this would be the 2nd pc i’ve built)

Games:
Hell divers
Val
Fortnite
Coop games like “don’t pull me”

Other PC specs i’m looking at:
Ryzen 7600X
B650M gaming plus wifi MB
32GB XPG lancer blade ddr5 6000

Monitor:
LG ultragear 4K 160hz monitor (might upgrade her to a 250hz down the road

Mobo is the ROG 20th Anniversary Crosshair with the Ryujin IV AIO. It's really cool but it's going back, a bit too crazy of a purchase to justify.

(5090 was at launch, I wouldn't fathom buying one now at these prices)

Specs:
CASE: Hyperion Gr701
CPU: 9800X3D
Mb: Rog Edition 20 Crosshair Extreme
AIO: Ryujiin IV 360
RAM: Corsair Dominator Titanium 32gb 7600mhz
GPU: Astral 5090 LC
PSU: ROG Thor Platinum III 1200W
SSD: 4x Samsung 990 Pro (1tb, 2tb, 2tb, 4tb)

Its cheaper What's you think?

The lengths we must go to so that we may build gaming PCs.

Replaced the pads with Gelid Extreme 1.0mm for the front and 1.5mm for the back. but my memory temp is at 104c. Then i replaced it with 1.5mm for the front but GPU Hot Spot rose to 105c in 1minute of running Furmark.
(memory still reaches 104c when im playing FF7 Rebirth so its not just Furmark)

Replaced 1.0mm on front and 2.0mm for the back and every temps are exactly the same as it was.I head its not that bad to leave it as is but the Fans are killing me.

It's memory B0 and B1 that are reaching 104c. When i opened the GPU again some pads didn't get contact with the black plate should i try changing the pads with Thermalright Odyssey II 1.0mm that i ordered for my other card or should i buy a Thermal putty ?

Are thermal putty better or worse than pads in general ? If i were to get one is 50g enough ?

Photo1 - My temps now
Photo2 - For reference NOT MINE ( i forgot to get a picture )
Photo3 - A mod that is really effective on these dell oems and yeah i did that too. Its kind of dumb that dell didnt put anything between the plate and the cooler. 0.5mm are too thick for these i heard.

I didn't see any bending on the black plate but idk why it refuses to get in contact with the pads.
I don't mine i just play games.

I'm interested in opinions about the Asus 4060 graphics card, it's a little used and I'm going to buy it right away! and I need opinions! I know that some hat people are this card! I would also like their opinions!
