Recieving warnings about the PCIE-1 slot temperature..

[Alanthor]

Hi,

I bought myself the ASUS Radeon R9 280X 3GB DirectCU II yesterday, and my motherboards thermal software "Thermal Radar" is alerting me about the temperature on PCIE-1. The alert pops up if it goes up to 60 degrees celsius. It event went up to 67 degrees celsius recently...

The actual GPU temperature is nothing to be worried about. Max measured is 75 degrees celsius in BF4 with ultra setting. But it seems to me that this "PCIE-1" in Thermal Radar isnt the GPU temp.. If I highlight the PCIE-1 slot in thermal radar, it says "This sensor detects the temperature around the PCIe x16 - 1 slot."

Conclusions?

Sounds like a temperature probe that is around the GPU. Considering the GPU temp can go up to 75C it is not surprising that the temp near the GPU would reach 67C the only way to lower that would be to get better airflow around the GPU otherwise you might want to raise the alert temp to around 70C instead of 60C

don't look like a good track record here on the card [if this is the one ]

I think im not able to modify the alert temps. But from what I have understanded, 70-75C isnt a issue. Is that info faulty?

Regarding my airflow, my case is very very old, approx 10 years old. Which means that there isnt so many options for me to do except "home made fixes".. I mean, there is 2x 80mm fan mounts at the rear. Both of them is exhaust fans. Then there is only ONE spot for a 120mm fan, and thats on the front bottom. And that fan is a intake fan. And lastly, my CPU fan (Hyper Evo 212), is mounted so the fan is on the right side, at the RAM. And its kinda operating as a exhaust fan aswell, cuz its blows the air to the left straight into the 2x 80mm's fans I have at the rear.
Maybe this airflow I have set is bad.. But I've heard that a negative intake flow is good or something like that. (To have more exhausts than intakes).

I could take one 80mm fan from the rear, and place it right under the GPU so it blows air right on it. But then again, maybe that will cause heat pockets etc?...

Edit - Thanks Junkeymonkey for that link.. I have been so happy about this purchase, I mean, the performance gains is unbelieveable! But jeez, it seems like the majority of the owner of this card is having some heavy issues with it... That sucks man 🙁

THOUGH! I just noticed. That GPU u linked is the factory OC'ed one. Mine isnt, so my gpu clock is 1.000MHz with 1.2v.

But im still worried, not about the GPU, cuz I know GPU's can handle 75C etc, but what about at the PCIe slot area? It's right beneath what I think is the Northbridge (NB HT), and I can also see a capacitor and such... Arent them sensitive towards heat?.. 🙁

I don't know if the slot is not supplying the correct pci-e power to the card

lets say the card needs the full 75w from the slot and for some reason the slot is only putting out 50w

All sizes of ×16 cards are initially 25 W; like ×1 cards, half-height cards are limited to this number while full-height cards may increase their power after configuration. They can use up to 75 W (3.3 V × 3 A + 12 V × 5.5 A), though the specification demands that the higher-power configuration be used for graphics cards only, while cards of other purposes are to remain at 25 W.

75w from the slot 75w from the 6 pin 150w from the 8 pin = 300w so what does your card require to run at full load?

I guess the best I could find at tech power up is max power is 298w [if this is your card??]

Uhm... What? 😛 Why do u need to know how much the GPU draws in load?.. Are u sayin that I should install the graphic card one slot down? According to my Sabertooth 990FX R2.0, i will loose performance. And no again. I do not have the "TOP" Version, aka the factory OC'ed version.

GPU-Z info: All values are taken from "Max measured"
12v = 12.06V
VDDC = 1.133V
VDDC Current = 127.5 A
VDDC Current In = 15.9 A
GPU Temp = 76C
Fan speed = 57%
VRM Temp = 70C

Keep in mind, all values above are what GPU-Z has measured at max.

Sabertooth -- theres your problem in my 14 years that's the biggest hunk of junk I ever used -- explained in the 9th and 10th post from the top

'Why do u need to know how much the GPU draws in load''

why would you not?? cause if your system cant support it then it will have these issues this is why things have min, requirements..

'' I do not have the "TOP" Version, aka the factory OC'ed version. ''
give me a link from asus or neweggg on it cause it looks like it discontinued or something cause I cant seen to find it

but i'll say now after our sabertooth experiences that's one thing I would look at ''defective''
