That's what I'm doing though, with MSI Afterburner and manually adjust the fan curve so it won't go as loud but I'm still concern with the temp.

By default, max temp were set to 83c

I'm using air cooling solution for my case, 2 intake fan and 2 exhaust fan. Case I'm using is Thermaltake V17 iirc (at work atm). Not sure how I should improve my ventilation better aside from opening the side panel itself
Yes, that's the GPU i'm using.

Just got back to test with side panel open, looks like it's still persist, maintaining 83c full load. Just 2c difference with no side panel open sadly

Test this with Monster Hunter World on ultra setting at 1080p. GPU usage at 98~100%


As above, I don't think this is case issue. I test it with side panel open, not much difference

Could I just underclock the GPU without affecting much of the performance? I mean, a 10% reduction in fps is negligible and not going to hurt the quality because from the benchmark I saw with this card, it's already quite overkill for 1080p.

I tried to reduce the power/temp limit to 91%/75c thru MSI Afterburner but it still kicking to 82~83c while it down clock itself from 1840MHz to 1700MHz when it hit the 83c limit

From the picture, Your card is clocked way above boost clock. I don't see any issue with your setup and suggest you just use it as it is intended.

The card is maintaining its set power target hence the raised clocks

To lower temps you would have to lower the clocks or power limits but you would sacrifice performance. Best would be to set the temp limit to your ideal temperature, but why change since the card is made to be set at 83C...

psu shroud too close imo. try remove those stupid cover

Yeah, exactly point on my fan model. Unfortunately i can only install 1 more extra fan which is below the front intake fan but I don't think it'll improve the air flow anyway since below there are where the extra cable resides.
I know that card is overkill but people from reddir (I asked) recommend to get it anyway for future proofing instead of getting 1660ti. Does this mean I have to forge another budget for better case?

The seller I go when I bought those case do recommend me to get the TT pure fan pack for like rm239 and he said it's a good fan to opt for but I still hold on from buying it yet. Need more advice for better case fans. Also can't find noctua fans at lowyat, probably need to survey more shops later.

All those front intake fan and top exhaust fan were wired to a 3-pin splitter to molex so can't really control much but low and high switch which I assume is 5v/12v switch

Huh, that's new for me, I didn't knew there was industrial ppc until you guys brought it up, definitely will look for it to assist with my air cooling setup build. Another thing that I learnt from the link you gave me, putting sleeve bearing fan (which is all of my current case fans) other than vertical position would have higher failure rate.

For PWM, I do need to get at least a controller right? My new case do not have built-in PWM support
My new case can support up to 7 120mm fans or 4 120mm x 2 140mm fans as the front panel can only support 120mm fan. I find this as no issue, as long there's 3 slot. I'm planning to replace those front panel fans as your suggestion with 2 or 3 industrial ppc fans while moving the current one to top intake. It would wear out the current fan but it's cheap to replace anyway. Later in the road, swapping those top intake fan to better fan or aio. Only concern with this setup is the type of airflow in the case.

Does the corsair LL 120 really good? I'm having doubt looking at the fan spec, about 40 CFM each which is like my sickleflow fan(?) Lets just say I'm ignoring all the fancy rgb and prefer performance.

Honestly, the heatsink on this card should belong to sub 120w GPU.
