What motherboard?

They can be on different headers just match the fan curves in the bios.

Its fine with no side panel on. As there is always fresh air. But once you have the side panel on it won't work so well.. You want the air to flow in one direction. Hence the term airflow. So you should turn it around

oops i mean the OP

need a better motherboard if you want to take advantage of a better cpu.

you don't, but its built to spec so it should be fine

1. you may need to tell the bios that 3 pin(DC) fan is connected to the specific header. 2. yes software will override the bios setting fan settings once booted to the OS. 3. the fun hub can be connected to any header. All fan connected to that hub will all operate at the same speed. some hubs have at least one connection where a fan(usually a PWM) need to connect to act as the sensor for the all the fans speed

yea people use them in u1 server case

It fine and it applies the same just the thermal mass is different(size and density, surface area of both contact point and to the air all have a factor. As I said it sounds fine. You should move forward.

Well its not a terrible thing. If its hot then you know that you have thermal transfer from the chip to the heatsink. Did you make a shroud too?

You could use only one. With 1 you'll have more options of placement. I think it would be cheeky if you added a 80mm rad on a single 80mm fan. Lol

True that those cases have poor airflow, but what style of lighting do you want? There fans with rings. Center lighting and more.

it not support officially, but they do fit

Custom loop vs aio are very different. I would highly recommend that you do not use an aio bottom mounted. If you want dual aio then top and front would be best. Aside from the air flow config I would use would be Bottom in Front in Top out You can also use 2x 80mm on the rear of the case.

its not far from it. its under the smaller heatsink right next to the cpu. technically it shouldnt affect the cpu temps, but i have seen people report better temps after re-pasting or NB cooling upgrades. i pretty sure it has something to do with power delivery being affected. you may even see a slight performance gain from it was really bad. at worst you'll know your NB is tak'in care of.

ii think i have an easier and most cost effective solution then what has been discussed. use some card board and tape to make a shroud/duct from the fan to the cooler. this should work well even if the shroud is 100% perfectly aligned on any side. also did you ever apply new TIM to the north bridge? This will help alot. its the heatsink next to the cpu cooler

Try running cinebench r20 and check your load temps.

Did you unplug the system before removing the battery? I also found the power cycling the system without the power cable and battery can be useful when clearing cmos.

There is no other cooler that will fit without zip tieing it. But it looks like your missing this shroud that directs the air from the fan through the heatsink https://www.ebay.com/itm/HP-Compaq-dc5800-dc5850-Heatsink-Cooling-Shroud-Fan-Duct-Intel-LGA775-463689-001-/114196649531?_trksid=p2349624.m46890.l49292

You can use any headed you want. You can control the pump speed just like a fan in the bios.

Thermaltake core series?

Best air coolers that should fit Be quiet dark rock tf Thermalright Macho 120 Rev.B Arctic freezer esport 33 You can use whatever fan you want. Just need to buy it. As for the aio The galahad is a good choice. The pump can be loud Ek aio is also a really good choice. When it comes to the header. .. It doesn't have to be an aio_pump header. It can be any fan header.

you can use anything 155mm or shorter.

moving more air to the gpu can only help if the gpu can move that air through the gpu cooler. I have found that removing the gpu shroud and fans, then zip tieing either 92mm or 120mm fans to the gpu is way way better then pointing at the gpu. it moves more air at less noise. depending on the gpu you can make this look really good too.

my GF build is in a 280x with a 240 aio top mounted. ram clearance isn't even with tall ram.( at least with my MB).. there are clearance issue with the EPS connection(the power connection at the top of the MB) tho. Some fit just fine. My corsiar fans fit no problem, but my arctic f12/p12 bionix (the ones that have the rubber ring around the fans blades) don't. i did get them the fit by cutting out a portion of the rubber ring( yes it does look good as long as you take your time and cut it nicely.) your 120mm uphere fan will only be "ok". they don't have good static pressure. which is helpful for both airflow in and through the case and through an aio. the other issue that I noticed is 120mm rgb fans on the front look weird AF(imho). Build likes these will defiantly give you hard time your not use to building in them or have more info before hand. you cant just buy stuff, throw it in there, and call it good like you would with larger cases. i wouldn't give up. i learned all these things the hard way too. but your end result will be even more worth it. If you want i can make recommendation list. but i need a budget.
