Correct after-market heatsink for P5000 (and RTX 3000/5000)

[Naberius]

Hi, all. Apparently I'm not done tinkering with my m17x.

 

I'd like to buy a new GPU heatsink for it. I have both the original 3-heatpipe heatsink and an aftermarket 5-heatpipe purchased from... eBay... (can't recall from whom though).

 

That said, my 5-heatpipe seems like it's a bit off in terms of layout (wherein it doesn't line up very well with the tail-end mosfets) so I'm looking to replace it.

 

(see this post for a picture of the coverage being... not great)

 

A recent eBay search brought up these by Cicichen

But I'm not actually sure if the Ranger gpu heatsink will fit in the R4. Anyone try it?

(I imagine I can reach out to Cicichen but I thought I'd ask here first).

The Ranger heatsink is slightly different than the M17x R4. One is slightly longer than the other but I can't remember which way it goes. I have tried it and I know that one fits in both but the other doesn't. My gut says that the Ranger one is the one that fits in both because I remember someone posting on NBR that they used Cicichen's Ranger heatsink in their R4. 

I have both at home so I can check but I won't be home until Friday morning.

I also once posted images of both heatsinks side by side, either on this forum or on NBR.

Appreciated! I could have sworn they were _mostly_ interchangeable (like, when i ordered my 5-pipe I seem to recall it was for either) but the purchase is far enough back that I don't have any records for it (which seems crazy but there you have it).

 

I uh... plumbed the nbr archive for a hot second... It's pretty wild in there!

All right--
So the currently available 5-pipe ranger heatsink from Cicichen won't fit in the m17xR4; the pipes and fins are longer and exceed the amount of available space in the chassis.

 

I've mounted up a p5000 on their current 3-pipe m17xr4 heatsink. That does fit.

 

I'm not sure what to do with the exposed memory on the back of the card though. I suppose I could sandwich in some silicone padding to abut them to the motherboard and do _something_. IIRC the 680m was mounted that way. Any thoughts there?

 

That said, I'm getting some interesting numbers off the p5000. First, idle temperature is higher (like 47c)... I suspected a bad mount until I ran a furmark test.

 

Furmark load test:

Temp: ~64c --> low but tracks with what appears to be a lower-wattage card

Board draw: ~100w

Chip draw: ~50w

Core clock: ~1570mhz

Memory clock 1500mhz --> very interesting there. IIRC 1070 cards usually run at 2000mhz

 

Firestrike: Graphics at 16000, which is some-ways off from the 17000-18000 on the 1070s I've had

 

Also, overclocking appears to be locked-out.

 

 

(Anyway - I'll start a new topic because this is getting into p5000 performance and operations)

Hi,

Quadros are LOCKED unfortunately.

And usually they have lower memory frequency than the geforce counterpart, that explains your lower scores.
