Hey guys, just finished the 98 build and everything works great. After finishing on the other hand, I started to think about the RPM which is what I probably should have thought out in the beginning (mistake). I have a 1.4GHz modded Tualatin with a copper socket 370 StarTech cooler. I replaced the 60mm fan with a 3-pin 12V Noctua NF-A6x25 FLX. I think the RPM for the fan is around 3000 while the StarTech fan was around the 4000 range. I felt the heatsink a little while it was running and it seemed a little warm but is that basically normal? Also yes the fan is facing the right side 🤣 Looking from the top of the fan is the intake side and is exhausting it onto to the copper heatsink. Also the PC has run pretty nice with not a lot of slowdowns, so I was just making sure that this fan and heatsink copper combo should be somewhat reasonable or optimal for the build. Thanks.

I think as long as it's not "ouch that's hot" when you touch it after running it with a full load for awhile it should be fine.

As long as the fan is spinning it should work.

Typically you blow down into the cooler but both ways will work.

On the side of most fans it has arrows showing the airflow and fan rotation.

The heatsink being warm is normal. If it’s too hot to touch there may be an issue. Lol just be sure there is thermal compound between the cooler and the cpu die

Awesome, thank you and everyone else. Was my fan placement not correct, I thought the exhaust side with the brackets should be sitting on the heatsink so the intake comes from the top and the onto the heatsink if I got that right. Just confirming.

It would help if we had pictures. But it’s hard to do so bad you have an issue.

This is from LGR's build but the fan is just like that.

Looks fine. I hate how the screws are messing up the fins but that won’t hurt much

True, mine isn't like that luckily 🤣 It goes into the sides and doesn't affect the heatsink at all, once again it is also copper 😀 Thanks man I appreciate it. Lastly, I just did a temp check with my hand at full load, is very cool!
