So... my E758-TR has a hot-headed VReg and it makes OCing my i7 930 anywhere over 3.6GHz impossible due to the heat generated from the voltages needed. Are there any fan coolers that I can buy for the E758 Vreg heatsink? I have a few 40-60mm fans laying around but need a safe way to mount those securely, any ideas on that part?

Once VReg temperatures go above 120ºC the PC will decide "enough is enough" and flash its "middle finger" BSOD and quit on me...

Ah, cool... as in put the fan on top of the heatsink and wrap a cable tie all the way around the whole thing? Always looked kinda risky to me

I always zip tie fans.  I've done it on heat sinks and currently I have three fans zip tied in my case.

Interesting... here's a picture of my VReg with its surroundings... not much space from what I can tell...



The cable left of the VReg is the CPU power connector... obnoxiously in the way. The 120mm fan on the left (rear fan) is actually an intake, i've installed the H50 radiator and push pull fans on the top of the case as an exhaust. Would you recommend fitting a fan on top of the VReg heatsink blowing down, or vertically next to the heatsink, blowing across? It'd be interesting to see how zip ties work to secure a fan in this situation... thanks!!

Last week I did a little revamp of fan placement after a trip to micro-center.
Picked up 2 Sythe 120 fans @ 110 cfm 1900 rpm and added them to my H50 in push pull and mounted them to 
exhaust out the top of the 932 case.

I didnt really like how the setup blocked the Vreg when mounted to exhaust out rear of case.
 
in this pic there are three fan layouts with comments all taken @ 72F ambient and at idle/no load 

 
Note the 3rd pic vreg temps drop. I cut up the plastic case 1 of the fans came in and made a shroud to funnel
approx 50% of the rear fan air directly through the vreg.
 
Couldnt get a good pic so mah paint skillz will have to suffice
 
Overview (kinda)

  I also added 2 more 120's exhusting out the top to replace the big stock fan that came in the 932.
Last pic / drawing shows the rear fan arrows as exhaust by mistake.
I did purchase 2 50mm mini-kaze fans to mount directly onto the vreg but wanted to see
if anything else could be done without adding noise or extra load on my psu.
Will get around to mounting them when I find the lost bundle of zip ties I have......somewhere.

central A/C on and set @ 72F
Everything was back to stock speeds again

Cool. 


I found the missing zip ties and plan to mount my fans 2 marow 

I've got the same issue. What I did was keep a 120mm fan blowing on the entire vreg. The temps don't go above 55c.
 
I just bought the 70mm fan and thought it would do the trick. But it does not have the pushing force that the larger fan does. Give it a shot if you have an extra 120mm fan.

To add:
 
Tell me if you have heard these symptoms before:
 
My (video card or motherboard) started to smoke a little and stink.  I turned off my computer, but couldn't see anything obviously wrong.  I turned my computer on again and it seemed to work fine.  But then, I started playing a game (or stress testing), and then my computer crashed.  Now it won't turn on any more.
 
What I just described is a pretty accurate summarization of a complaint I have read from time to time.  The cause of the complaint is burning voltage regulator modules. 
 
The voltage regulator modules work in parallel with eachother. As one fails, the others take up the load; this causes them to fail at an accelerated rate a short term later.

I hate to say, the biggest problem you have is the EVGA heatsink.  I have yet to see a single quality heatsink on anything they make.  That "sexy" coating on whatever material they are using doesn't help much to cool it down.  If its not naked copper, it ain't right.

I should make a VR heatsink for that board out of pure copper. 
Consider me inspired...

 
Yeah, the vanilla X58's Vreg heatsink is awful.  I have looked for aftermarket heatsinks before; no luck.  Why can't I find an aftermarket one?

Nate you want those pics? I can have them for you on Monday.

 
side pieces for lateral stability, while screwing from underneath.  I could probably bang it out in an afternoon once I get all the dimensions and do all the coding for it.

So you have no need for said designed cooler? 

is anything directly above the vregs?  about 4" straight up.

your getting rid of your H50 for an air cooler?

your getting rid of your H50 for an air cooler?

 
I read too many reviews on how the Megahalem can beat the H50 at higher overclocks and with the right push pull fans. Besides, with an H50 there is no airflow around the CPU area causing my VReg temps to skyrocket.

I have a Megahalems for sale, depends where u live tho as shipping could be more expensive than buying a new one if ur in the US

 
Let's talk! PM me a for sale post just like you would do in the marketplace
