North Bridge/Hyper-Transfer Bus Overheating

[Sanyu_]

Hey there everyone.

So I recently built my first desktop and I need some help with figuring out why my NB and HT are running so hot. I've got an AMD FX-8350 overclocked at 4622.5 MHz(215 Base, 21.5 Multiplier) running on an MSI 970A SLI Krait Edition ATX motherboard, with a Silverstone TD02-LITE 240mm AIO cooling the damn thing. Here's the full parts list: https://pcpartpicker.com/list/GhmJQV. I've dumped an additional .15v into the processor and have been able to get it at least somewhat stable. Here's the problem though; if I have my side panel on my case, the base idle temp for the NB/HT is about 74C, when the MB and CPU Package temps are at 32C and 40C respectively.

I have my case fans in the default configuration, with 3 front intakes and 1 rear exhaust, and my AIO top mounted with a pull configuration using some 1500 RPM Thermaltake Radiator fans. I have also removed all but 1 of the hard drive mounts to lessen the restrictions on airflow.

If someone could help me figure out what it is that could be causing this, I'd be extremely grateful!

ht doesn't really make heat, its a wire

 

The north bride always runs hot, its a old design.

 

Don't worry about nt temps, thats normall, it will last many years at 80c

problem is that it gets up to 86C-90C load and then blue screens...

is there a oc on the cpu? thats probably your problem, its very unlikey the temps are causing the bluescreen.

yes there is an oc. the base clock speed of a FX-8350 is 4.0 GHz with a 4.2 GHz Turbo. I have it overclocked to about 4.623 GHz. But it's stable when I have my side panel open, and was stable with it on during the winter when I first built it.

get rid of the oc if there are any stability issues first.

I 100% understand that if I get rid of the oc, it would become stable again. However, if I get rid of the oc, my gaming performance and rendering performance take a huge hit. So, I think you can understand my reluctance to drop the oc flat out...

then only lower the OC a little ... maybe to 4.5 GHz ... 

 

you say it's stable with the side panel open - does that also include the fan blowing on the mainboard like that ? 

 

maybe mounting a small fan on the NB heatspreader might help. 

 

these here are not loud at all and might move just enough air: https://www.amazon.com/Noiseblocker-NB-BlackSilentFan-40x40x10mm-Silent-3800RPM/dp/B00ZB7TD4G/ref=sr_1_2?ie=UTF8&qid=1498068771&sr=8-2&keywords=Noiseblocker+BlackSilentFan+40mm
